Well, we can't allow for total freedom.
Before and after heroin.
Of course heroin and cannabis are radically different. But the freedom to use what you wish... Well, that would legalize what is shown above.
Strong images, I know. but, the ones I chose are mild. There are much worse examples.
People in their twenties looking like they were 50. And deathly ill. Skinny as needles. With huge open sores all over their bodies. What few teeth they have are rotten. Eyes sunk in and voice completely without life and character.
Again, this is not anything close to cannabis. But we cannot legalize this hell. Because hell it is. A hell it could cost you your life leaving after just one shot. And it will cost you your life if you stay in the hell of heroin abuse.
It cannot be legalized, and a clear line should be drawn. I say we draw that line at cannabis. The effects of a high last for such a long time you are affected negatively for days after a high. It could increase traffic accidents, and it would reduce overall school performance if it became any more commonplace. It would harm our competitivety internationally.
The beauty of alcohol is - if you get drunk you are generally fine after just a day of hangover. Same can't be said for cannabis. The effects are much much milder. But they dissipate too slowly.
