Medical Weed vs. Illicit Marijuana: Know the Differences

Understanding the differences between reliable providers and illegal market sources of weed is crucial when it comes to legal compliance, quality assurance, variety, safety, and accessibility. It is always recommended to choose sources that adhere to legal requirements and standards to ensure a safe and trustworthy cannabis experience.

1. Legal Status

  • Medical Weed: Legally obtained under specific regulations and prescribed by qualified medical professionals.
  • Illicit Cannabis: Obtained outside of the legal framework without a prescription. Possession, supply, and cultivation are illegal in the UK.

2. Quality Control and Standards

  • Medical Weed: Undergoes strict quality control measures, ensuring safety and efficacy. More specifically, licensed producers adhere to specific regulations, including testing for contaminants and consistent dosage.
  • Illicit Cannabis: Lacks quality control measures, potentially exposing users to impurities, pesticides, or inconsistent potency.

3. Purpose

  • Medical Weed: Primarily used for therapeutic purposes to alleviate symptoms and improve the quality of life for patients with epilepsy, mood disorders, chronic pain, and more.
  • Illicit Cannabis: Often used for recreational purposes, where the user seeks the psychoactive effects produced by cannabinoids.

4. Accessibility

  • Medical Weed: Strictly regulated and requires a prescription from a specialist doctor, following particular guidelines. Also, it involves patient assessment, review by medical authorities, and obtaining a specific license.
  • Illicit Cannabis: More readily available through informal channels, but quality, safety, and source cannot be guaranteed.

5. Varieties and Strains

  • Medical Weed: Available in a carefully regulated range of strains tailored for specific medical conditions.
  • Illicit Cannabis: Comes in different varieties but with inconsistent labelling and documentation, making it difficult to determine characteristics and effects.

Understanding Cannabis Quantities and Their Costs

When it comes to purchasing weed in the UK, understanding the common measurements is crucial. The most widely used measurements are as follows:

  • Gram: The smallest unit of measurement, typically used for small purchases or sampling different strains.
  • Eighth: Equivalent to 3.5 grams, an eighth is a popular quantity for regular users.
  • Quarter: Equal to 7 grams, a quarter offers a larger quantity for those who consume weed more frequently.
  • Ounce: The largest common measurement, an ounce, is equal to 28 grams and is primarily used for bulk purchases or sharing among friends.
Quantity/Quality Low-Quality Weed Medium-Quality Weed High-Quality Weed
Gram £5 to £10
Eighth (3.5g) £15 to £25 £20 to £30 £30 to £40
Quarter (7g) £30 to £45 £40 to £60 £70 to £90
Ounce (28g) £80 to £120 £140 to £180 £200 to £280

Note: The prices mentioned are approximate and subject to change based on various factors. 

Low-quality Weed

Low-quality cannabis, often referred to as “brick weed”, is known for its compressed and lower-grade nature. The cost in the UK can range from around £5 to £10 per gram, £15 to £25 per eighth, £30 to £45 per quarter, and £80 to £120 per ounce.

Medium-Quality Weed

Medium-quality marijuana offers a step up in terms of potency and overall quality. The approximate price range in the UK falls between £20 to £30 per eighth, £40 to £60 per quarter, and £140 to £180 per ounce.

High-quality weed

High-quality cannabis ensures the best effects and flavour and is used in medical prescriptions. The prices for high-quality weed typically vary between £30 to £40 per eighth, £70 to £90 per quarter, and £200 to £280 per ounce in the UK.

Factors Influencing Weed Prices: What You Need to Know

Weed prices can vary depending on several factors. Understanding these variables is key to making informed decisions. Let’s delve deeper and explore the key considerations that influence cannabis prices:

Legal Status

In countries or states where marijuana is fully legalised and regulated, prices tend to stabilise and more accurately reflect market demand. Conversely, in regions where cannabis remains illegal or is only available for medical use, prices are generally higher. This increase is attributed to the risks associated with cultivation, distribution, and sales in these areas.

Furthermore, according to a United Nations Office on Drugs and Crime report, cannabis prices are generally lower in countries that produce or are near production areas, like Afghanistan, Morocco, and Jamaica. Conversely, countries that import marijuana, like Europe, tend to have higher prices, ranging from £4.78 to £24.08 per gram, as stated by the European Monitoring Centre for Drugs and Drug Addiction.

Quality and Strain of Cannabis

As also highlighted above, premium strains with elevated THC content and more desirable effects typically command higher prices. Rare, difficult-to-grow, or unique strains may also be priced at a premium. Lower-quality or less desirable strains may be available at a lower price point.

In addition to this, the global demand for high-quality weed is increasing, leading to a significant rise in the cost of a gram. According to Forbes, the average price increased from $7.36 per gram in 2017 to $8 per gram in 2019.

Supply and Demand Dynamics in the UK Cannabis Market

The demand for marijuana versus the available supply is a significant driver of prices. If the demand exceeds the supply, costs are likely to be higher. Conversely, if the supply outweighs the demand, prices may drop.

Various factors, including popularity, production fluctuations, and consumer preferences, also impact supply and demand. Canada serves as a prime example where the legalisation of recreational cannabis in 2018 initially led to a substantial price hike due to insufficient supply. However, as the industry evolved and met the growing demand, cannabis prices eventually decreased.

Geographical Factors

Geographical location plays a role in weed costs. Prices may vary across different regions within the UK due to transportation charges, proximity to cultivation centres, local regulations, and competition among suppliers. Urban areas may have higher prices due to higher demand and operating costs compared to rural areas.

To provide a clearer representation, the table below provides a snapshot of the cost differences in cities across the UK:

City Average Weed Price per Gram
London £6.72
Birmingham £8.58
Manchester £7.92
Glasgow £7.24
Leeds £7.42

How Much Is Medical Cannabis Prescription and Treatment?

When considering medical weed, it’s important to assess the overall costs, which include not only the product but also the associated consultation, prescription, and ongoing treatment. Importantly, charges for appointments and treatment expenses can vary among healthcare providers and depend on individual needs.

Comparing the Prices of THC and CBD Products: Which Is More Expensive

When it comes to comparing the prices of THC and CBD products, there are several factors to consider, including the product type, quality, and the specific form in which they are available. That said, THC medications generally tend to be more expensive than CBD ones due to several reasons:

  • Legal restrictions: THC is psychoactive and has more stringent regulations compared to CBD.
  • Production costs: THC products often undergo more intricate extraction processes to achieve desired potency levels.
  • Higher demand: THC products are sought after by recreational users, which can drive up prices in some markets.

CBD Price Variations: Full-spectrum, Broad-spectrum, and Isolates

CBD products are further divided into three different types, depending on their content:

Type Description Price Range
Full-Spectrum CBD Contains all naturally occurring compounds found in the cannabis plant, including THC (within legal limits). £20 to £100 per bottle for oil tinctures
Broad-Spectrum CBD Similar to full-spectrum but with the THC completely removed. £20 to £100 per bottle for oil tinctures
CBD Isolates Pure, isolated form of CBD without any other cannabinoids or compounds. £20 to £80 per bottle for capsules


Key Takeaway

Determining the cost of weed in the UK is a complex matter influenced by several factors, including quality, type, and origin. However, by understanding these factors, you can make informed decisions when purchasing cannabis.
