If you are intent on insufflating your d.o.c....being an addict myself I realize sometimes urges can trump logic and science. I have been using roxis extensively and for a good period of time, so hopefully I can help here. Basically just BE CAREFUL, start by blowing one or two and wait 20 mins to gauge effects. If you're not satisfied maybe do half doses until you get what you want. Everyone's different so you may be chasing a feeling you can't get anymore because of your tolerance. Better to do too few, than too many.
