No, it literally just stopped having any effect on me. It's not like I ever took much - once every 6-9 months or so, for about 2 years - but at some point it just didn't do anything for me. I tend to have an extremely high resistance to pretty much anything. Caffeine. Pain killers. Recreational drugs. And I don't take anything on a regular basis. I even have a fantastic collection of single malt scotch whiskys, and I will have maybe one or two drinks a week. In fact, I wanted to get high the other day on cannabis. But it doesn't have much effect on me, usually. So we went to the cannabis store, talked to the pros there, and the woman gave me two different tinctures to try out. (I had previously tried the Legal Weed coffee drink, which has 40mg of CBD in it, and it had almost no effect on me.) I finally found my sweet spot! 50mg of CBD. FIFTY milligrams!! And it takes about 2 hours to take effect. So yeah... I don't do any sort of drugs often because it simply isn't very predictable.
Due to its lack of desirable effects on me, I have little to no knowledge of how cannabis, or any of its components or compounds, actually work. Or what they mean. For example, I have no idea what the relationship of CBD to THC is, or even what they stand for. I had to google the Legal Weed drink I had, because I knew it had "40 of something" in it, but didn't know the measurement used. (I think it is 40mg.) So ... I know some of the words in your comment, but am not really equipped with the background info to understand how it applies to me... I feel kinda derpy right now, honestly! :-)
In very general terms: CBD is a semi-legal anti-inflammatory, anticonvulsant, possibly tumor suppressing, pain reducing compound found in cannabis. Delta-9 THC is a psychoactive compound found in cannabis, responsible for the high. Both are found in the plant and breeds have been developed that contain high amounts of either or both kinds. CBD is semi legal, in that you can buy it, possess it, but the process of producing it involves growing cannabis which is still illegal for those of us living in the dark ages. Also, most CBD extract or tincture has some amount of THC present. Not enough to get a buzz, but enough to fail a drug test or catch a felony for possession.
That helps a lot. This makes conversations with my parents (CBD users) and my wife (THC user) make WAY more sense. Yeah, I went to the pot shop to get high. Not to get healthy. So they provided me with the sativa tincture I needed to get my 50mg dose that finally had the desired effect.
