As more individuals utilize cannabis for both medical and recreational purposes, understanding the involvement of cannabis in testosterone levels has become increasingly relevant. Understanding the interaction of cannabinoids and the hormonal systems that affect health is valuable information for the users.

Overview of Current Scientific Evidence

There are many studies looking at the testosterone and cannabis interaction that have shown mixed results. It has been suggested from some studies that acute usage of cannabis may reduce testosterone levels in the short term, while longitudinal studies have shown little impact on testosterone levels. The challenge of definite conclusions surrounding testosterone and cannabis is complicated by the complexities of the endocannabinoid system and individual variations.

Acute Effects

Acute cannabis use has been suggested to suppress testosterone production in some individuals. Cannabis will suppress testosterone production within a few hours of consumption, have effects for 24 – 48 hours, and it would return to baseline levels. The effects are from phytocannibinoids on the hypothalamic-pituitary-gonadal axis, which regulates levels of testosterone.

Chronic Effects

The chronic use of cannabis has shown more complicated patterns with testosterone levels. Some studies have shown that chronic use impacted and somewhat reduced testosterone after several months, while other studies have suggested that the body will adjust over time and get back to baseline testosterone levels. The effects of cannabis on testosterone are heavily influenced by individual variables such as: age, health status, and amount and frequency of cannabis consumed.

Effects of Dose and Frequency

The relationship between Testosterone and Cannabis appears to have a dose-response and frequency component. Regular heavy daily use will influence hormone levels different from engaging in casual or moderate use. The delivery methods will also have an impact on hormone levels. Due to the nature of smoking cannabis, there may be different impacts on testosterone levels than whether an individual used edible or vaporized cannabis.

Variability

There are genetic and individual variability factors such as: age, sex, and baseline hormone values, that will influence how cannabis will impact testosterone production. There may also be greater effects in younger men compared to older men who may be less sensitive or responsive to the acute aspects of cannabis use. The existence of previously medicated hormone conditions may also play a role in how cannabis would impact testosterone levels.

Recovery and Reversibility

The literature suggests that most cannabis-induced testosterone changes are reversible upon quitting cannabis. The majority of studies have suggested that hormone levels return to baseline within a couple weeks to couple months of ceasing cannabis use, however, the rate of recovery will depend on the individual. As the changes to hormonal levels will reverse, this suggests to the reader that effects of cannabis on testosterone are likely to be functional, not permanent.

Clinical Significance

For males with low testosterone or considering testosterone replacement therapy, cannabis use should be addressed with clinicians for both therapeutic use and assessment of any effects on testosterone. There may be educational and practical overlaps between cannabis and hormone treatment considerations, and it is best for the user’s health to engage healthcare providers.

Lifestyle Considerations

Exercise, dietary choices, quality of sleep, and stress management may all affect hormone levels and likely interact as well with the effects of cannabis use. Engaging in a holistic and proactive lifestyle will mitigate the potential negative effects of cannabis on hormones.
