Personally feel horrible after using THC but I can use hemp products without THC even with large amounts of CBD anyhow used to smoke THC constantly then just seemed to randomly become allergic to it.
I can eat THC and minutes later almost faint
I feel ya personally used to smoke isolate and bud constantly without any problems then suddenly anything with THC makes me feel like I am about to die even eating 5mg
I used to love cannabis and use it constantly in high THC then suddenly started nearly fainting with even low THC edibles.
