Yes, meth can cause psychotic breaks, especially if you through in the lack of sleep that usually occurs with a meth binge.
How ever, if he is on psychoactive drugs rxed by a doctor, he can hallucinate if he screws up the dosage without any ill intent.
I made this charming discovery last night when I forgot to take my Celexa in the morning when I usually take it. Around 3 AM, I woke up with a jolt. I looked over to see if Thomas was laying in his usual position next to my head, and instead saw my late BFF's corpse laid out in bed next to me.
I didn't freak. I knew I was hallucinating. I looked at things and said, "Oh Sh!t" blinked a few times, and the image reverted back to Thomas. I went back to sleep and woke up about half an hour later. Lather, rinse, repeat. Until 5AM when I got up and counted pills. Sure as heck, I'd missed the celexa and was hallucinating as part of withdrawal. Popped a celexa and things got back to normal within a couple of hours. Rather an unpleasant experience. I'm just glad that I was mindful enough to know I was hallucinating, and that it was probably related to my medications. Lucky also that for some reason, waking up with a corpse next to me didn't scare me right off the deep end.
Had I gone to ER, I would've been admitted on a 72hr hold.
I also lost a call center job due to a bad reaction to Lamictal that had me shaking, sweating, staggering and incoherent. I was fired for being intoxicated on the job. They refused to cooperate with my pleading with them to take me to the industrial clinic and do a blood or better yet, a hair test. Worst yet, my cell phone was dead, and they wouldn't let me use their phones to call a cab as there was no way I could drive. So, I had to sit outside the building, in my car, until the lamictal reaction wore off, and the drive(very carefully) home.
