Unlike in situations where powdered substances like heroin, cocaine, or meth are laced with fentanyl – with marijuana, you can sometimes notice a visual difference. If you see white specks inside of your weed, it could be laced with fentanyl.

Other times, people report smelling strong chemical scents similar to paint thinner, and say they associate that with fentanyl. It’s not advised to taste or smell a substance to see if there is fentanyl in it as those are two common ways it’s ingested.

If you want to be certain about whether or not there is fentanyl in your weed, fentanyl testing strips can be used to detect fentanyl within a substance.

Whether you smoke it knowingly or not, smoking fentanyl-laced weed is considered polysubstance use. Polysubstance use occurs anytime you have two or more different substances in your system at the same time.

Fentanyl is a synthetic opioid, which is a type of depressant. Depressants, sometimes also referred to as downers, tend to slow down the body. They can cause feelings of relaxation and help with sleep and pain relief.

Marijuana can act as both a depressant and a stimulant at times, though it is primarily a depressant. This means for most, it causes relaxing effects, but for some, it could also cause a boost in energy and alter your perception of reality, as well.

When you mix together two similar substances, it may increase the speed at which you feel the effects but it can also increase your risk of an overdose. In the case of depressants, it can slow down your breathing and heart rate to dangerous levels when you have too much in your system at once.
