sounds like a pretty big generalization to make - theres no way that all the weed is laced lmao alot of the time weed itself is cheaper than synthetic cannabinoids, so its not profitable to be lacing it a good rule of thumb is to be suspicious of weed you buy thats already chopped up - if someones lacing they do this to get a better surface area of the synnies imo i doubt its happening very often, i always hear weed-noobs talk about laced weed but seasoned stoners don't seem to think it happens too often
