I've wondered this my whole life, if marijuana is relatively harmless, why do parents hate it when they let us do many other things that are worse for you. They disregard facts of how it can help you and only look at the negatives, picturing everyone who smokes a "low life" and I don't even think it's the effects that they care about, if you think about it , if THC was put into a pill form and sold to help patients with pain, parents would see it as a medicine, but because it is smoked , it gives a bad view on it , comparing it to cigarettes as they are very bad for you.
