Long-term effects of using marijuana include:
Enhanced cancer risk
Decrease in testosterone levels and lower sperm counts for men
Increase in testosterone levels for women and increased risk of infertility
Diminished or extinguished sexual pleasure
Psychological dependence requiring more of the drug to get the same effect
Another false claim states that marijuana lowers male testosterone levels. This claim is a scare tactic that is still widely used by the United States government. The hope is to scare boys/young men into believing that marijuana use would "turn" them into women.
Low testosterone levels are associated with underdevelopment of the growing male body, a higher pitched voice, and slight breast enlargement. This theory has been challenged/refuted by several studies: Block, 1991; Mendelson et al., 1974; Coggins et al., 1976 (3).
