hi, I’ve never been seriously addicted to anything but have a history of drug use. When I was younger I experimented with drugs a few times. I have used mainly psychedelics, weed, but predominately most of my usage stems from psychiatric drugs ironically. I also have an addiction to coffee and need it to function. The amount of times I’ve used anything but weed is quite small, as well as the dosage. The question I have though, how much does a person need to take for one to experience or have caused memory problems? My memory used to be alright but now my short term memory is in the low side of average. It may be depression, stress but I am not sure. I am just really curious, though about this in general m. I’ve also taken Valium twice, and Xanax daily for one month(just one why I quit) 2 years anti depressants, two months adhd drug, and then a few months anti depressant years later along with sleeping pills. Thanks.
