You should always be careful when getting prepackaged marijuana, even if it’s from a trusted trusted sources. Pre-rolled joints alone could include things like synthetic marijuana, crystal meth, PCP, and crack cocaine. It can cost a ridiculous amount to test every batch of weed you get from a less that reputable dealer, so here are five ways to tell if your weed is laced with something by using your senses.

Trust Your Eyes

Before you grind up and light up, always take a good look at your bud for more than a picture to post on the ‘gram. Make sure that the trichomes on your plant look legit because there have been instances where shady dealers try to add laundry detergent or little pieces of glass to make bad weed look better. Even worse, some crushed pills and other drugs can be sprinkled on top of a bowl to look like kief. Another telling sign is if when you go to light the bowl, there is a lot of sparking and popping. Sure, sometimes you get shwag weed with seeds in it and they pop, but if the popping is more than a little constant, the weed may be contaminated.

Trust Your Nose

We all know (and a lot of us love) the smell of fresh marijuana in the morning… or vaped marijuana.. or smoked marijuana. If your bud doesn’t smell quite right, first and foremost, check for mold. After no mold is confirmed, be aware of the possibility that whomever grew the bud initially did not do a complete flush and there could still be pesticides and other harmful chemicals still in the plant. If the smell gets worse, or stops smelling like cannabis all together, the weed could be laced with another drug. It’s probably a good idea to put that stuff down.

Trust Your Tastebuds

Despite the harsh feeling that the irritants in cannabis leave in your throat when you smoke, it shouldn’t necessarily taste bad. When you inhale the smoke, it makes a pass over your tongue and tastebuds. If the weed tastes like an unflavored chewable aspirin, it may be laced with something. Another thing to watch out for would be an extra harsh feeling in your throat and lungs, especially if you’re an experienced smoker.

Trust Your Body

You know your body better than anyone. The side effects of indica and sativa strains are different, of course, but if you’re experiencing more extreme symptoms, something could have been in your bud. Memory loss, agitation, insomnia, excessive energy, and an overwhelming sense of euphoria. Most of those symptoms are easily associated with specific hard drugs that can be mixed with cannabis.
