Is it true that smoking marijuana affects erections the same way smoking tobacco does?

Yes: Marijuana and low testosterone: the two go hand in hand. Yes, marijuana is a "herb". Yes, marijuana is a "natural plant". However, none of that is going to change the fact that marijuana is a one way ticket to low testosterone, erectile dysfunction and fertility problems. The political debate regarding marijuana may be interesting, but the research shows it to be debilitating and harmful.
