One reason is political, a lot of money and research is going towards understanding crank cocaine and its impact, since the powers that be have noticed that drug problem. A blended version of these says that it may boost your immune system up to a point, but that it also boosts HIV production, so you end up losing the gains over time. The truth is probably even more complex. We do know managing HIV infection requires good nutrition, keeping a higher balance of vitamins, building lean body mass, exercising and sleeping regularly. Crystal meth use, even only occasionally, can lead to forgetting HIV medication routines, skipping meals due to loss of appetite, depletion of vitamins and losing weight, and staying awake for days at a time.
Crystal stays in the body for about three to five days after use.
Using crystal can also cause dehydration and mood swings when one is tweaking or crashing. It can be a lot of stress on a body. Also, there was the overdose of a man who was taking ritonavir and two tabs of ecstasy, which is a similar amphetamine. The drug company was reluctant to study the problem, but there may be a few of us who are vulnerable to strange interactions between HIV medications and amphetamines. Well, think about the male psyche and one reason could be due to some HIV medications leading to a kind of impotence.
