However, it's important to note that the relationship between marijuana and depression is complex. Some research has suggested that regular and heavy marijuana smokers are at a higher risk for depression, although a causal link between cannabis use and depression has not been established.
For many people with HIV, the use of ART has increased their CD4+ cell counts and decreased the amount of HIV in their blood (viral load). These beneficial effects help to reduce the risk of developing a life-threatening infection. Neither AZT nor any other anti-HIV medication is a cure for HIV.
This is because the active compound of AZT, known as zidovudine 5-triphosphate, has a high affinity (attraction) for an enzyme called reverse transcriptase, which is used by retroviruses such as HIV to replicate viral single-stranded RNA (ribonucleic acid) into proviral double-stranded DNA (deoxyribonucleic acid).
