My CHS started when I moved to California 10 years ago. Nearly all the cannabis at the time caused me significant digestive issues, vomiting and pain. It took me about 3 years to figure out where the problem was coming from. The last 7 years are where I've tested aza breakdown times in cannabis with my own grows, and tested cannabis treated with neem products from other grows.
Anything with neem/aza in it causes problems. Light contamination takes days to weeks before the problems show up. Heavy contamination has symptoms showing up immediately. Dabbing heavily contaminated causes instant problems. The time delay effect with lightly contaminated has been the biggest problem. Dabs made with lightly contaminated cannabis have a much higher concentration than flower and can make recognition/symptoms show up quicker.
there is no independent evidence of this....there are cases of CHS that do NOT involve neem/aza strongly suggesting other forces at work.
I can dab or smoke as much "clean" cannabis as I want. Zero issues. If aza wasn't a cause of CHS, the last 10 years would have been SIGNIFICANTLY different for me. Being incapacitated in your mid 30's, to the point you're using mass opiates and a walker, is massively scary. Especially when every doctor you talk to throws up their hands and says, "I have no idea what's going on."
the use of neem oil does NOT make mine or anyone else's cannabis 'dirty'.
So, for me it's strictly aza related. The last year without growing my own has been a nightmare. The best thing which happened this year was getting rid of the overblown H.Pylori infection which caused continued digestive issues after each aza poisoning. I'm now 30 days into flower, so things are looking up.

sorry you get sick, but the language and tone of finality you use in your posts weakens your message. there are many, many of us that DO use neem/aza and have done for years that do NOT have any of the experiences you describe. would love to know exactly how many people are suffering from CHS....and the number of people using neem treated pot without any problems?
for those that are interested,here is a link to the Bio Pesticides Registration Document for Neem Oil.: https://www3.epa.gov/pesticides/che...registration/decision_PC-025006_07-May-12.pdf
