"Suppositories are more effective than traditional methods of cannabis medication administration due to its their superior bioavailability, meaning they’re easy for the body to use and process. It has been found suppositories have an efficiency rate of up to 70 percent, whereas inhaling cannabis is estimated to be up to only 25 percent efficient. Other methods of consumption are even less efficient, for example eating cannabis is only about 20 percent efficient." (GivingTreeAZ.Com)
