Effects of chronic marihuana use on integrated plasma testosterone and luteinizing hormone levels.

Integrated plasma testosterone and luteinizing hormone levels were determined for 13 healthy adult males before, during and after a 21-day period of marihuana use. No significant relationships were found between antecedent or concurrent marihuana smoking and integrated plasma testosterone and luteinizing hormone levels. All values for all subjects obtained during the entire study were within normal limits for healthy adult males.
