Brix or Brixx is a commercially available cutting agent used to increase the weight of cannabis. Produced in Australia and America, Brix is widespread and not without risk. So-called Brix can consist of many materials; the main components are various types of plastic and sugar, often hormones. Immediately after harvesting, the female hemp flowers are dipped in Brix or sprayed while they are flowering and then dried. Brix contamination creates serious health risks.

Distinctive features

In its raw state, Brix initially looks like perfectly normal, fresh & wet marijuana. However, it seems like that even if the grass should already be dry.

Another distinguishing feature that shows very clearly that it is a synthetic extender is the taste test. According to many consumers, Brix causes a burning sensation on the tongue and has a chemically sour or bitter-salty taste. However, this identification is strongly discouraged, as it means that you come into contact with the extender, which can be very toxic.

Arguably the safest way to ensure that the marijuana is without Brix is ​​to burn a small amount of the material in question. If there are characteristic sparks or if it burns very poorly, then there is a high probability that the grass contains Brix. In addition, the produced ash during combustion is very hard. If you crush this ash and a greasy, black oil film remains, it is Brix.

Health risks

Since consuming marijuana contaminated with Brix is ​​smoking liquid plastic, the short- and long-term consequences are severe. In particular, considerable problems with the respiratory tract have been reported. Coughing with phlegm, shortness of breath, and trepidation are a few typical side effects of consuming herbed grass. It releases substances that can cause cancer. In addition, plastic can modify our genetic material and can cause severe consequences for evolutionary development.

Other impurities

The market for cutting agents is immense: many different products and agents are in usage to increase the weight of cannabis flowers. It makes detection very difficult for consumers.


It is challenging to tell whether marijuana has been contaminated with lead, lead dust, or lead sulfide. The all too small, dark splinters shimmer little. Some recommend a pocket microscope to check whether cannabis contains lead. It is a highly harmful extender; even a single joint can result in a lengthy hospital stay. The substance is deposited in the bone substance and releases toxins into the surrounding bone and tissue structure.


If you perceive cannabis as sweeter than usual, it could indicate that it contains sugar. Because sugar is a cheap and easy-to-use substance, it is a standard extender of cannabis. First, one dissolves the sugar in boiling water, spraying it onto the cannabis plant after it has cooled. When the water vaporizes, it leaves a sticky trail. White sugar gives the buds an ashen appearance; brown sugar can be more challenging to identify as it appears more visually similar to the trichomes. Sugar-soaked marijuana burns poorly and leaves a hard ash. Standard glucose tests (paper strips) can provide a quick and reliable statement of whether it is sugar-soaked cannabis.


Glass particles are usually not very difficult to see with the naked eye. If there is glass in cannabis, one can identify it using a pocket microscope. Health risks are scarring in the lung tissue. When burned, the glass particles burst and get into the respiratory tract. If so-called “glass grass” is consumed for extended periods, it can lead to silicosis and, worst case, complete lung failure.

Pesticides and Fertilizers

The fungicides, pesticides, and fertilizers often used to combat stem rot are serious health risks that can alter nerve functions and damage the nervous system. In addition, asthma symptoms are often associated with the consumption of cannabis that is afflicted with plant growth agents and the substances mentioned above. Toxin residues can remain in the buds for a long time.


It is hard to avoid that small amounts of sand and soil enter cannabis naturally in outdoor cultivation. Although, intentional contamination does exist. Cannabis with sand crunches between teeth; this weighting method can be easily recognized and revealed.


Spraying cannabis with hairspray produces a pungent, chemical taste and fragrant smell. The solvents carry a high risk of cancer. Hairspray is also highly flammable.

Talc, Soapstone

Talc is a matt white shimmering mineral – a different name is soapstone. This mineral should make marijuana appear more resinous and gain weight. A grass contaminated with talc appears white without the typical smell.
