None of my searches reveal anything like my own personal experiences when looking at studies on THC side effects.
I have had problems with a loud hissing sound in my ears and a nasty facial twitch on the whole left side of my face for about 3 years now. According to my records this coincided with when I attained a medical marijuana card. I ran out of that batch about 2 weeks ago and switched to some new stuff. The facial twitch, hearing loss, and hissing in my ears has completely stopped for the first time in that 3 years. Would you say coincidence or strong reason to suggest a connection? Over the past 30 years I have experienced a variety of side effects all different from different batches. Most common was a small painful spot on my head just above the left ear. It would usually last for seconds and then disappear. Most serious was severe arrhythmia in the heart.
No supposedly unbiased study I have ever read suggests anything like these. I am starting to think they just go unnoticed or the connections are not being made. I never suspected for a minute my ear problem was pot related. I did suspect the facial twitch.
I’ve been a regular weed smoker for 20+ years. Re Indica vs. Sativa strains, honestly I have never been able to discern much of a difference. I know, I know, Indica strains supposedly make you sleepy and relaxed while Sativa strains do basically the opposite. But not to me.
Also, I’ve never heard of problems arising due to mixing strains. There are so many mixed strains out there, they have varying percentages of Indica/Sativa.
I just realized another possible side effect I was getting. My stools went back to their normal shape and consistency since I ran out. They were kind of screwed up for the past few years that seem to coincide with that particular purchase.
Mixing strains isn’t generally an issue. I usually keep strains apart but I’ll put the leftover dregs into a general container. However, in this case mixing may be an issue if one strain causes you problems.
Also, I am going to guess that after three years more problems may arise from dried out bud. There is an ideal humidity level for freshness and taste. I am not sure if overly dry flower can be an issue but it is possible. What is the best way to store pot? If you don’t consume at a great pace, something like these are good for long term moisture control.
I like mine with just enough moisture that it has a slight clumping quality to it. If it starts drying out I just add a little water to it. I store in a cloth drawer in an airtight Tupperware container
