Grit Weed: Everything You Need to Know About Marijuana Contamination

Grit Weed

Ever since the legalization of cannabis, the practice of purchasing the herb from the black market has lost almost all its popularity. Marijuana is legal now for medical and recreational use in various states of the US. And given this, there are many government-certified places that are selling it.

However, in any terms, we cannot say that people aren’t visiting black market dealers at all. For one reason or another, the cannabis black market is still working.

But do you know what’s the biggest concern while buying your products from the black market?

No, it’s not being caught or getting into any legal trouble, but the chances of getting contaminated products. Now, the problem here is that if you buy a bad product from the black market, you cannot even call the police. Furthermore, in the past few years, the forgotten concept of “grit weed” has also surfaced again, adding a lot to the concern.

So, isn’t there anything you can do about it?

As a matter of fact, you can. By knowing what the grit weed exactly is, and how you can identify it, you can save yourself from it. And today, we’re here to help you with this exact thing.

So, shall we begin?

What is Grit Weed?

The cannabis plant can be contaminated in various different ways. And grit weed is one specific type of contamination. We categorize a product as “grit” when the cannabis bud is contaminated with silica glass. The main motive behind this is to make the product heavy so that the dealer can get a good price for it.

The problem of grit weed was very prevalent in the UK a decade back. But the users soon discovered a nice and quick way of determining if it is grit weed or not. We’ll talk about that in the later sections.

Other Types of Contaminations

You should note that adding silica glass to the product isn’t the only way black market dealers contaminate cannabis. There are many other ways of doing that. And here are a few of the common ones.


Do you really believe that all growers use organic methods to grow cannabis? If so, then you are badly mistaken, my friend. The harsh truth is money talks. And growers don’t want to lose money by losing their crops to pests. As a result, they use pesticides.

However, some amount of these pesticides can stay stuck to the buds even after they are dried, cured, and stored. And these chemicals can be very harmful for your nose, throat, and lungs.

One way to save yourself from this problem is to buy your supplies only from a trusted seller who thoroughly check their products for pesticides. For instance, if you live in LA, you can always apply for a medical marijuana card online in Los Angeles, and find a good dispensary nearby.

Residual Solvents

One of the best ways of extracting the cannabinoids, terpenes, and flavonoids of the cannabis in oil form is to use the CO2 extraction process. By using CO2 as a solvent, you leave not a single thing behind after the process. However, this isn’t the case with other solvents, like butane. With these types of solvents, no matter how hard you try, there will be some traces of the chemical left behind. And in some instances, the oil can also have these chemicals.


There was a study conducted in the year 2017 that discovered something very disturbing. As per the study, even cannabis from registered dispensaries can have impurities. The researchers involved with this study tested the products from a legal dispensary in California. And they found that the product contained various different types of fungi on it. The most common ones, they say, were powdery mildew and grey mold.


The same study also discovered some traces of gram-negative bacteria in the dispensary products. The cannabis had the presence of E. Coli, Klebsiella pneumoniae, and various other bacteria that may be harmful for you.

What Dangers Does Contaminated Cannabis Possess?

You probably already know how dangerous is it to consume contaminated cannabis. But here, we’ll put some more light on the problems you may face.

First of all, by consuming bad marijuana, you may have to face extreme pain in the chest. And in some extreme cases, if there is no treatment readily available, it may even prove fatal. Some users may also have an allergic reaction if they consume contaminated cannabis products. This may include inflammation in the eyes, an itchy throat, and excessive production of mucus.

Grit weed also poses extreme dangers to your lungs and other body parts. Fungus and bacteria can severely damage your respiratory system. And other side effects may include:

  • Vomiting
  • Diarrhea
  • Pain in stomach
  • Headaches
  • Nose Bleeding
  • Rash
  • Eye irritation

In some extreme cases, the patient may also feel difficulty in breathing, palpitation, convulsion, and unconsciousness.

How to Find if Cannabis Is Contaminated?

One of the most effective ways of keeping your hands off contaminated cannabis is to get a medical marijuana recommendation in LA and buy from a trusted source. If you prefer the convenience of purchasing cannabis or CBD products online and are eager to explore new unusual consumption methods, consider visiting specialized websites or discover Best CBD on AskGrowers.com which caters to a wide range of innovative and unique options from different reputable brands. We recommend you try different CBD products from such brands to receive a pleasant cbd experience But as we saw before, even the products from cannabis dispensaries aren’t always pure. And thus, it’s a good idea to have the knowledge on how to identify good weed from the bad.

Here are a few ways you can differentiate between a good and a bad cannabis product.

  1. Sound
  2. Look
  3. Feel
  4. Smell
  5. Taste


This particular way of checking the quality of your cannabis is very useful in determining if the product contains silica glass or not. In this method, you rub your bud against a piece of glass and check if it is making any scraping noise. If yes, there is a very high probability of your product being grit weed.

You may also try rubbing the bud on a CD and check for any scratches due to the glass in the bud.


Check for your product for some green/gray fuzz or any powdery speckles. If you find any of these, the product is most likely moldy. To confirm this, you may take a small hit and check the ashes. If it is forming hard and totally black ash, the cannabis is toxic. In this case, the ash also doesn’t fall off easily when you tap the joint.


Place the bud between two of your fingers and check if it is dry and crisp. If yes, then it isn’t moldy. However, it doesn’t mean it is pure and free from all contamination. But if the product feels damp and spongy, it is most likely moldy. A powdery texture bud may also mean it is mixed with something else.


Given a different terpenes profile, each cannabis strain smells uniques. However, the aroma the cannabis plant gives out, in general, is quite musky and a little sweet sometimes. So, if your product smells way too sweet, the chances of contamination are high.

Furthermore, if your bud smells like a farm or fresh cut grass, avoid consuming it. Most probably, it isn’t dried properly.


While smoking cannabis, the taste should be all-natural. So, if your weed tastes like some chemicals etc., there is probably something wrong. Of course, there is an exception if it’s a unique strain that actually tastes like that.

You may also place a little of your product on your tongue. And if it tastes too sweet, most likely it is contaminated with sugar.

In the end, you should keep in mind that consuming contaminated cannabis can be very dangerous for your health. And in some cases, it may land you in a hospital too. So, as advice, you should avoid buying your products from the black market altogether.

Instead, apply for a medical marijuana recommendation in Los Angeles, and buy only from trusted sources. The chances of getting a bad quality product are far less here. And even if you, unfortunately, find something contaminated, you can always identify it using the above-given methods.
