I KNOW sublingual is 40-50%. I BELIEVE nasal is ~60%.
A bit higher. I personally take them sublingually, strips or tabs. Although right now im prescribed strips (since ih ave 0 urge to sniff them). Some people swear by sniffing subs: i used to? but honestly sniffing them now is so disgusting to me that I cant do it. Plus for whatever reason sniffing suboxone makes me sneeze like NO OTHER DRUG, and i just personally feel that sniffing subs does not work as well as it should because I end up with a shitload of orange powder covering my nose that im sneezing all over, despite me doing not huge lines (like .5-1mg).
Just tickles my nose in the wrong way. I wonder if other people feel this way about sniffing subs?
