Er der nogen herinde der ved om cannabis virker negativt på hormon balancen i forhold til træning?
Jeg har kigget lidt rundt på nettet efter svar, da jeg hørte rygter om at det skulle være dårligt for hormonbalancen, Men det ser ud til der er forskellige meninger om det.

In the 35 years since the active compound of marijuana,
9
-tetrahydrocannabinol, was isolated, the psychological
and physiological impact of marijuana use has been actively
investigated. Animal models have demonstrated that
cannabinoid administration acutely alters multiple hormonal systems, including the suppression of the gonadal steroids, growth hormone, prolactin, and thyroid hormone and
the activation of the hypothalamic-pituitary-adrenal axis.
These effects are mediated by binding to the endogenous
cannabinoid receptor in or near the hypothalamus. Despite
these findings in animals, the effects in humans have been inconsistent, and discrepancies are likely due in part to the development of tolerance. The long-term consequences of marijuana use in humans on endocrine systems remain unclear.

Abstract
To investigate possible effects of chronic marijuana use on reproductive and stress hormones, we assayed testosterone, luteinizing hormone, follicle stimulating hormone, prolactin, and cortisol in 93 men and 56 women with a mean (+/- S.E.) age of 23.5 +/- 0.4 years. Hormone values were compared among groups of subjects stratified according to frequency of marijuana use (frequent, moderate and infrequent; N = 27, 18, and 30, respectively) and non-using controls (N = 74). Chronic marijuana use showed no significant effect on hormone concentrations in either men or women.
