Re: marijuana, well, I can tell you that a leading ferret vet who excels in endocrinology said that he considers it unsafe to expose ferrets to marijuana. BTW, wouldn't it be a sorry shame if some of the adrenal or common adrenal complication (anemia, prostate problems, etc.) cases out there were due to marijuana's documented effects on estrogen levels? (Documented in boys just entering puberty according to past discussion with a breast surgeon who had to perform mastectomies on a series of such teens who were apparently especially vulnerable to the effects. Ever notice how marijuana used during the most vulnerable years of change in humans gets lost in discussions of endocrinological abnormalities?) Unless a substance has been proven safe for ferrets don't assume it is. Such assumptions have killed ferrets when they were given Tylenol and an assortment of other OTCs (over the counter medications), so it would be foolish and unloving to take the same sort of risk with any thing else, including marijuana. Let's face it, it just does not make sense to give a substance which messes with the endocrinological balance to an animal so prone to endocrinological tumors. Studies of the compounds in it, though, may leads to useful drugs which don't have such a potentially negative side effect. [Posted in FML issue 4317]
