I love this question Joe! Unfortunately this is a hard one to answer. There isn’t one specific strain that I can say is the “worst” in a general classification. For example, personally, I hate the cannabis strain “Green Crack.” It makes me paranoid, jittery and just plain weird. But, I have friends who LOVE “Green Crack,” so this is a personal preference. The best thing to do is keep a cannabis journal, write down the strains you try and how they make you feel. Then you will start to see patterns in your preferred products.
