I have heard cannabis suppositories have a significantly higher bioavailability than other delivery methods. This is one source I found on a quick search, but I have seen others which place oral efficacy well ahead of smoking, but still behind suppositories.


I'm a little skeptical of exact percentages as there are various factors that come into play. Combining it with a carrier oil can affect absorption and there is debate over which oil is best. There is a whole area of research you can get into over medium-chain fatty acids vs long-chain, coconut vs olive, etc. Here is a forum page I just found with a discussion on that subject, but I encourage you to dig a little more if you're interested. This was just the first thing that popped up.
