LSD addiction?

[Psychonautica]

Swim thinks that the addictive properties of lsd should be reconsidered as she believes she went through lsd addiction for several years in high school and is currently witnessing several friends spiral down into the same binge spiral that she did. Swim doesn't think that there is anything in particular contained in lsd that makes it physically addictive, but believes that many users can easily become psychologically dependent on it.
At first swim said that she'd drop maybe once or twice. Of course, acid was more fun than she had anticipated and at xxxx bucks a tab, no way she'd pass them up. Swim loved everything about lsd. It was easy, just eat a tiny little square of paper and she was good for 18 hours. The drug was especially appealing as an alternative to mushrooms, which are very very hard to stomach for swim. Also swim loved that she could have a good time in public and social situations while frying, something which was much too awkward and scary for swim on mushrooms. She quickly went from buying 1 or 2 tabs at a time to buying 10, then 20. She went from dropping every frew weeks to every weekend to multiple times during the week. She would even drop acid during school and calculate how long it would take to get to wherever she was going after school so that she would be able to drive before peaking, but optimally be peaking when she got there. One time she tripped for 4 days in a row, taking 3 tabs on the first day, 3 on the second, 2 on the third and exhausted, having not slept at all, and totally fried still managed 2 more tabs on the fourth day. In short swim's lsd use very rapidly escalated, she was always thinking about tripping. Any time sober was spent bitterly thinking about how much sobriety sucks and all of swim's energy was put into planning the next trip. She became delusional and believed that living in the lsd world was the only possible way she could happily exist and was determined to permanently destroy reality and achieve "perma-trip".
She was coming down from meth and lsd when she moved to Canada for college and decided to quit using both for good and start a new life (she has since stopped using neither).

Swim is honestly very sick and tired of lsd. She's been there and back and there and back again, and is still a little bit out there. She suffers from constant persisting hallucination, is constantly tripped out and seeing and hearing things. Swim has "flashbacks" every single day, but experiences some level of hallucination all the time so only considers the emotional and mental disturbances triggered by certain hallucinations to be a "flashback". Though swim is ridden with anxiety and paranoia, to her horribly dismay, she still finds herself wanting to drop acid if for no other reason than habitual.

Two months ago swim was at a party where there was acid, and just being around it for the first time in a long time was too much and after 4 months clean of lsd, swim dropped again. It was a pretty dramatic experience, she didn't come down for nearly 3 days and believes that one more tab and it will certainly be the permanent deterioration of her sanity. The thing is, swim STILL wants to drop acid. The only reason she hasn't is because she has kept herself away from it for the last 2 months, which has meant not associating with many of her friends. Friends who are currently binging on lsd, bitterly hating reality and yearning for the several days a week when they can fry, just like swim did in high school.

Lsd has made it's permanent rainbow brand on swim's life. Swim feels ready to quit taking it, but there hasn't been one time when she was around it and didn't use it. What can this be called other than addiction, strong psychological dependence? And people told swim that lsd wasn't addictive...
