*Disclaimer: I'm all for legalizing it and taxing the hell out of it.
Now... I question many things in that pic
Non-addictive? Really? Perhaps not as much as tobacco or alcohol but a little less than half of users do develop dependence and actually exhibit withdrawal symptoms while in rehab.
Cures cancer? Not in a million years. Cancer patients manage pain with it.
Grows/heals cells? Nope. When smoked, it's more damaging to the lungs than a cigarette.
side effects: Short term memory loss. Spacing out. Since THC gets absorbed by fat... the effects can come back for weeks. In other words... you can space out while driving weeks after smoking (more pronounced the more you used since you last stopped using... if that makes sense to you).
Just broke my personal record for number of consecutive days without dying!
