Well... we consume water everyday and that's essential for survival, while daily consumption of MJ is not for everyone. I've watched a BBC docummentary about mental issues, which had a section about THC and it's potential to induce psychosis in some low percentage of users. That's an exception, but there are general long term effects too. I'm rather skeptical about some, e.g. that about decline in IQ I saw [here](http://www.drugfreeworld.org/drugfacts/marijuana/short-and-long-term-effects.html), but so I am about claims that MJ cures cancer. Maybe it does, but it requires far more research and positive peer reviews. Not the first and not the last time when there are sensational news about wonderful cures that after time prove to be not working or harmful. That said, I think ganja has big potential in medicine, e.g. in alleviation of seizures, but I'm not so sure about treating cancer.

I haven't done much research as I wouldn't call myself a ganja user (I tried it few times, for recreacional, not medicinal reasons), although I don't think water is an adequate comparison. More so would be, imho:
- sugar as some scientist alarm about harmful effects of high intake of it, including allegedly negative effects on brain (while others disagree)
- or porn. I haven't done much research on it's effects either, but I found BPS's video ["MGTOW and the CANCER of Porn on Society"](https://www.youtube.com/watch?v=WKcxOqvty3c) interesting and he linked to a post where he references what the video is based on. I don't think anyone has ever died from a daily fap, but it's not w/o some adverse effects.

Am I a coward or a tool for commenting like that?
