BTW, you can get an idea of the scientific research in the field yourself by using the medical research database: www.pubmed.gov. You can search the database yourself using any search term you want

Here's what I found (emphases added):

"With reference to chronic substantial cannabis use and its impact on brain function, the definitive studies are yet to be done. If clinical impressions are meaningful, some people, especially young people, can sustain temporary and perhaps permanent impairment of nonintoxicated mental performance." - https://www.ncbi.nlm.nih.gov/pubmed/6973305

In other words, more research is needed.

Fedzilla needs to let real research occur and end the unconstitutional prohibition against cannabis.

That is an article from 1981. A *lot* of research has been done since then, which has confirmed and added details about how marijuana causes damage at the cellular and molecular level. And more research is still needed.

There was pretty much a research desert until this big experiment with quasi-legal marijuana began a few years ago. Now, a lot of researchers are interested in the subject, since the potential threat to public health is so high.
