Medical Cannabis vs. Illicit Marijuana: Know the Difference

In the midst of the global cannabis debate, it’s crucial to understand the distinction between legal medical cannabis and illegal street marijuana, particularly in the UK. Here’s what you need to know:

1. Legal Status

  • Illegal street marijuana: Cannabis, in its raw form, remains illegal in the UK. Possession can lead to a warning, a penalty notice, or even arrest and potential conviction, which could result in a prison sentence.
  • Medical cannabis: On the other hand, the UK legalised cannabis for medicinal use in November 2018. Patients with specific conditions can now obtain a prescription and use it legally.

2. Quality and Safety

  • Illegal street marijuana: When purchasing from an unregulated source, there’s no guarantee of product safety or quality. There’s a risk of contamination, and the actual content of THC and CBD can vary significantly.
  • Medical cannabis: Prescribed cannabis undergoes rigorous testing and quality control. It is cultivated under controlled conditions, ensuring that patients receive a safe and consistent product.

3. Benefits of Legal Medical Cannabis

  • Travel-friendly: With a prescription, patients can travel with their medication even across international borders (though always check destination country regulations).
  • Police encounters: If found in possession by law enforcement, a valid prescription will shield you from potential legal complications.
  • Standardised potency: You know exactly what you’re getting in terms of THC, CBD, and other cannabinoid levels.
  • Workplace assurance: Should your workplace conduct drug tests, a prescription offers a legitimate reason for the presence of cannabinoids in your system.
  • Peace of mind: There’s an undeniable comfort in knowing your medication is legal, safe, and consistent in its effects.

Why Does Cannabis Smell the Way It Does?

Before we delve into strategies for odour elimination, it is important to understand the compounds for the distinct smell of cannabis. The plant contains a variety of volatile organic compounds, including terpenes and cannabinoids, which contribute to its unique aroma.

These chemicals can be released during cultivation, storage, and consumption, leading to the strong smell typically associated with the medication. The distinctive scent is often described as “earthy”, “skunky”, and even “pungent”. For medical users, controlling this smell is crucial to maintain discretion and ensure privacy.

The Role of Terpenes

Central to understanding the smell of marijuana are terpenes. This diverse class of organic compounds produced by cannabis plants is responsible for the unique scent profiles of different strains. Beyond their olfactory contributions, terpenes have been studied for their anti-inflammatory, anti-anxiety, and pain-relief properties.

Odour and Quality Perception

Interestingly, the aroma of cannabis is also intertwined with perceptions of quality and potency. A 2017 study published in the journal PLOS ONE indicated that individuals often associate distinct aromatic profiles with varying levels of quality and strength, even though the scent is not a reliable indicator of either.

Cannabis Smell: Challenges and Considerations

The following are some challenges and concerns medical cannabis patients and healthcare providers face when dealing with the pungent aroma.

For Healthcare Providers

  • Stigmatisation: The smell of cannabis may evoke the stigmatisation rooted in its history as an illicit substance. Some healthcare providers might subconsciously associate the scent with recreational use, potentially impacting professional perception.
  • Scepticism: Despite the growing body of research supporting the therapeutic and clinical benefits of this alternative medication, some specialists remain sceptical regarding its medicinal validity.
  • Professional dilemma: Healthcare providers might struggle with reconciling the traditional views of cannabis with its emerging role in medicine. The scent serves as a constant reminder of this dilemma, potentially influencing their recommendations and patient interactions.

For Patients

  • Preconceived notions: Patients who have not used this medication might have preconceived notions and biases. The scent might be associated with unlawful activity or certain stereotypes, potentially impacting their willingness to consider or adhere to medical weed treatments.
  • Anxiety and apprehension: For some patients, especially those unfamiliar or uncomfortable with cannabis, its scent might induce anxiety or apprehension regarding its use, effects, and the potential social stigma attached to it.

At Lyphe, we empathise with the challenges providers and patients face with medical cannabis treatments. Our goal is to support you in navigating these obstacles and delivering optimal care. We encourage patients to consider different treatment options while also assisting providers in making informed decisions about medical cannabis suitability.

Strategies to Minimise and Neutralise Cannabis Odour

While the odour of medical cannabis treatments may linger within a given space, there are a number of methods that can be implemented in order to minimise or neutralise it.

Proper Storage Techniques 

The first line of defence against smells is adequate storage. Airtight containers help seal in the scent and prevent it from dispersing. Using odour-absorbing materials, like activated charcoal, can further minimise the scent.

Here are some additional tips for proper storage to avoid any scents from escaping into unwanted territory:

Tips Description
Material matters Opt for glass or high-quality plastic containers that are specifically designed to prevent air exchange, thereby containing the scent of the stored medication.
Size appropriateness Choose a container size that closely matches the quantity of cannabis to minimise excess air and potential odour leakage.
Odour lock Vacuum-sealing cannabis in bags before placing them in airtight containers offers an additional layer of protection.
Location consideration Place the storage box in a location that is accessible yet not in direct line with common areas to minimise any potential scent dispersion.


Proper storage of medical cannabis is not merely a matter of preserving its quality but also a demonstration of respect and consideration for the shared and personal spaces of others. Hence, implementing effective storage techniques can help ensure that patients can utilise medical cannabis as per their therapeutic needs while maintaining a smell-free environment.

Ventilation and Air Purification Methods

Good airflow and ventilation are essential for preventing the build-up of odours in indoor environments. When it comes to air quality, there are several techniques to ensure that the air in your home is clean and fresh.

Ventilation: Ensuring Optimal Airflow

  • Strategic airflow management: Implementing an airflow management system is the best way to get rid of weed smell. This might involve utilising exhaust fans, opening a window, or employing air movers to prevent the scent from becoming stagnant.
  • Negative air pressure: This is a condition where the air pressure inside a space is lower than the pressure outside. It can help neutralise the smell of cannabis by creating a pressure gradient that pulls air, along with the odour, into the space, preventing the scent from escaping to the surroundings.

Air Purification: Targeting and Neutralizing Odours

  • Activated carbon filters: Widely recognised for their efficacy in odour management, activated carbon filters can adsorb and neutralise the volatile organic compounds (VOCs) found in cannabis.
  • HEPA filters: When used in conjunction with other filtration technologies, HEPA filters can enhance the overall air purification process.

Additional Tips to Reduce the Smell of Cannabis

  • Combining ventilation and purification: Utilizing air purification technologies in tandem with effective ventilation ensures a multi-faceted approach to managing cannabis odour.
  • Routine maintenance: Regularly servicing and replacing filters and ensuring ventilation systems are functioning optimally is crucial to sustaining effective odour management.
  • Localised solutions: Employing localised solutions, such as desktop air purifiers or localised exhaust systems, in areas of frequent use can provide additional support.

Managing the scents of medical marijuana through adept ventilation and air purification not only ensures discretion but also enhances the comfort and acceptability of its use across varied settings.

Odour-Masking Techniques

If eliminating the smell is not possible or practical, odour-masking techniques can help. The following are some of the best ways to neutralise the smell of cannabis:

Method Item/Type Description
Essential Oils Lavender and peppermint Used to mask cannabis scent when diffused
Citrus scents (lemon, orange) Refreshing and effective in neutralising persistent odours
Incense Variety of fragrances Masks the smell of cannabis and neutralises the environment.
Natural options Incense made from natural resins and botanicals ensures a cleaner burn and authentic fragrance.
Odour Absorbers Activated charcoal Absorbs and neutralises odours when placed in areas where weed is stored or used.
