Priest I think you are overreacting or you don't have any self-control or maybe.. a sad childhood, if you had it isn't anyone fault taking down the ladder would be better for you too, if you haven't had any freedom again isn't anyone fault. As far as looking at your kid, miss/mrs or mam and your name would be?... Okay. Shrooms like weed isn't a drug.
I think you should allow him to grow shrooms because they have potentinal for being open-minded, free, accepted & see beyond everything. If you want to learn more about drug education our community it's your best choice ( Suggestion > Psyhedelic Medicine and other subforums of ours, we are a harm reduction community and we want the best for everyone). They treat numerous diseases and isn't a party drug as far as myself take a peak at, your trip it's meant to be in a controlled space and it's used mostly for rituals, meditation and connecting with your higher-self with peaceful sounds. IT DOESN'T CAUSE ANY KIND OF HARM.
Be happy that your son/daughter it's inclinated towards shrooms because there are other real drugs that could cause real fuckin harm ( oxy, H, Ice aka Meth, Slide, etc). My advice would actually be to leave him be, don't think about stupid stuffs like dealing or things like that because your kid isn't doing any of these and let's say he/she would? Do you know that people who earn their $ on illegal ways are living far better than people who live by society rules? nothing new in most people eyes sure. Do you know that whatever it's legal it's killing you and what it's illegal it's healing you? Not all of them but 98% I say they heal.
Last words to end.. educate yourself, mam. Your kid it's doing a great job and If it were my kid I would help him.
