I can't comment on the latter though it may be dangerous to operate machinery or drive just like that's true with SSRIs. Then again, the same might be true with an upper, like Ritalin, or anti psychotics. But the reverse could also be true. Someone with f.e. ADHD who uses Ritalin might be able to be a better driver _due_ to the Ritalin.
As for the former,
1) its widely documented and I can personally attest that marihuana caused anxiety attacks, including one clear case of a psychosis, in numerous occasions.
2) It is also known that people who suffer from schizophrenia should stay clear from marihuana. The same's true if they have a relative who suffers from schizophrenia. Why? Elevated risks to trigger a schizophrenic episode
3) I worked in a Dutch coffeeshop and know that, to put it black-and-white: sativa gets one high, while indica gets one stoned. There's also a lot of hybrids though, as well as some conflicting info. Decent website is Leafly [1]. I was wary to give tourists sativa, as well as spacecakes which we also sold. I recommended them different things instead (including: not buying). My boss didn't give a shit though, as long as people were 18+.
For a good movie about the subject of drug-induced psychosis, see "Das weisse Rauschen" (The White Sound) [2]. Although in this movie the drug which causes the trigger is "magic mushrooms" this movie still takes a good shot at what a drug-induced psychosis could look like.
