Wrong. MJ use can be tempered, exactly like alcohol use. And MJ has so many beneficial qualities, unlike alcohol.
The usual denial that there's anything wrong with pot.
We KNOW that alcohol can be abused. Obviously. But there's a contingent on the forum (started by you-know-who) that insist that there are no side effects or addiction problems with pot. That simply is untrue. It can cause serious addiction, and has serious side effects. It can be used medicinally, as Fr. Scott says, but with supervision. For good reason.
The reason for smoking pot is to get stoned. And when stoned, people do stupid things, some of which are sinful, as LT says.
