Actually, by having done loads of research on the subject (needed to write a research paper on the stuff), I've actually found out that marijuana is far better than cigarettes. No I'm not a pothead. I have smoked, but a long while ago. But a single blunt actually only does one third the damage to your lungs that a cigarette does. And with that being said cigarettes are very addictive, so it keeps adding on, whereas marijuana is purely a psychological addiction. Yes, people can get addicted to it, but rather than their body being addicted to it like cigarettes, they develop a mental dependence on the substance. As for the sensory impairment, this is true for some people (not all), but the impairment wears off with the high. Don't mistake me for a pothead, I'm just stating it seems to be so much better than cigarettes that pay a much worse toll on your body. Also, it may not be as bad as cigarettes, but when you're high, your judgement is much worse than before (depth judgement and whatnot while driving). Remember kids, don't drive under the influence 😉
