If your sister has hallucinations on weed, please ask her to find a doctor. I have an acquaintance who is a neurologist specialized in cannabis, weed doesn't cause hallucinations unless the person has some predisposition to mental health issues.
About the drug in the game, could be mdma(ecstasy) or ketamin, and yeah, I have a great deal of experience with drugs lol
Weed gives hallucinations, that's a common fact. For medical cannabis it's rare, because of the low content of THC, tetrahydrocannabinol. Natural cannabis has often much higher halt of THC which can cause hallucinations*. Medical cannabis also has a high content of CBD, cannabidiol, which lower the risk of hallucinations. So was the neurologist talking about medical, he's right. If he was talking about natural, he was a big liar.

I worked in a pharmacy company, Master in Chemistry, so I know this. Even if I didn't work in the department that was researching cannabis. (I know a lot more about ulcers medicines!)
*Never happened to me, I found smoking weed a very boring thing to do, but a friend jumped into a fishing net decoration on the wall and screamed he was Jesus. So he crucified himself in the fishing net. In the end we had to use scissors to cut him loose, he was so tangled in the net that we couldn't get him free. Still today I'm laughing so I cry thinking about that!
