Sorry you are misinformed......as with any substance it can cause harm if abused and does stimulate phsycosis in some people....It saved my children's life as both suffered severe head injuries with life long complications. My one daughter uses it for constant pain. The other uses it for epilepsy. Both have a quality of life thanks to marujana. Neither has experienced any damage in fact both are successful in demanding fields. I use it for creativity and my brain is in excellent health. I also used it for my father when he was diagnosed with Parkinsons and it gave him good quality of life till he passed....

From vast experience, I can say that smoking weed or hashish has done less damage to my liver than drinking alcohol. When I was taking opioids for chronic pain, I could halve the dose of oxycodone by smoking a joint or part of it. Not able to do any significan work during that time, but at least i was not crying out in pain every few minutes. That greatly disturbed the dogs!

It’s not just brain function, that is important. It’s other organs well being too. I smoked and drank for a while. My body wasn’t that happy. I quit drinking, and all my organ functions improved. I know that my cognitive functioning is impaired with high marijuana use, but the resulting emotional resonance is more than worth it.

Well alcohol has never been an assist to clear thinking...leaves you feeling like shit and is basically destructive both biologically and mentally.
Pot is helpful to getting aha moments in ones thinking and does less harm, assists creative thinking and helps sleep....also assisted health.

No comparison.
