I've found that I never feel anything off smoking or vaping. My body seems to require high doses so I use high dose gummies and RSO concentrate. That stuff is great.
When I get to that point I just quit smoking for a while. Doesn't take long to lose your tolerance. In my case when I return it only takes a hit or two to get me pretty stoned, and I do my best to leave it at that point for as long as possible.
Never heard of RSO myself, but even with my high tolerance. If I come home from work having abstained for the day, I get pretty baked off one or two hits. My issue is a day like yesterday, a lazy day at home when I smoke in the morning and then end up smoking throughout the day and never achieving that same high I had from my first hit in the morning.
