Can Smoking Weed Lead To Tinea Vesicular?

Can weed lead to Tinea Versicolor? I've been smoking weed for sometime now. Before when I got high I used to have similar problems to the ones I read about on this site. over the past year I started to get really sick to the point where my family sent for me to get medical treatment. I am currently back in my hometown and I've been diagnosed with HIV +. I've been taking treatment for about a little over six months now. When I first started treatment I didn't have any severe side effects. Its now six months later and I'm in much better health. Since I noticed my health getting better I started back smoking. That would be around January of this year. The paper that I smoke in is a brown paper as oppose to the white one that I used to smoke in. Shortly after the year started I realized I started itching and now I have a mild case of what I know it to be called "Tinea Versicolor." I was wondering if this could be from smoking weed or from smoking it in the brown paper. I've never had this problem before. I think it could either be a side effect of my medication, the difference in weed or the difference in the paper that I roll the weed in. These three things are the only different things my body has come into contact with since I moved back home. I really enjoy smoking (I smoke about one or two joints a day) but I'm wondering if this could be the cause of my newfound Tinea Versicolor? my doctor has prescribed a shampoo for me to use for only 3 consecutive days. I'm very self conscious and I would like my skin to clear up soon- do you think weed is the cause of this? Based on my research is does not have weed or smoking as a cause. Would smoking weed cancel out my treatment? (that is the pills i'm taking) I read that it could stem from a weakened immune system or imbalances in my hormones. I'm a bit confused since I've been taking treatment for about 6 months now I would like to think that my immune system is stronger instead of weaker.....please advise me
