I'm curious of any known negative health effects of weed? I know it doesn't kill brain cells, but does it hurt your memory in other ways (long term? short term?) Does it have any negative effects on the lungs? ...If i was to vap every since day would it hurt my brain or body in any way!? Iv been smoking for about 11 years, and vaping for about a month (if that) so I'm not new to weed, but I'm unclear if it has been hurting my brain or body in any way... Thanks guys.
