I am rather sick of people touting the dangers of marijuana smoke.

1) Even if "per hit" it's worse for you than cigarettes, no one smokes twenty joints a day. As far as I know, there are no well-documented cases of anyone developing lung cancer *solely* from using cannabis.
2) No one is screaming here about criminalizing cigarrette usage, so the marijuana smoke is really a non-issue.
3) You don't have to smoke it! I only vaporize and eat it these days.

Honestly, I've been using cannabis almost every day for a long time, and the only negative side effects I've noticed are

1) I went from 120 to 145 pounds. As I was considered anorexic for my height, this is actually a benefit. Marijuana has stimulated my appetite, leading me to eat healthier amounts of food.
2) When I don't smoke one evening, I tend to get stressed or depressed. Of course, this is one of the reasons I smoke daily anyway, to relieve stress and depression that were already there.
3) When I get completely fucking blazed, I feel a little fuzzy-headed the next morning.

Now, here's what happens when I drink:
1) I lose my inhibitions and act irresponsibly.
2) I vomit for hours.
3) I have a terrible migraine the whole of the next day.

Granted, a lot of stoners smoke every single day, multiple times, and this is not particularly healthy--but there are people who drink several times a day, and they tend to develop serious behavioral problems and die an early death (which does not happen to stoners).

There is NO WAY weed is worse for you than alcohol. Absolutely no way.
