Here is a quote from an article written by a colleague here at HelloMD,
"Effects can usually be felt within 15 minutes of ingestion. For medical marijuana patients who need fast relief from symptoms that come on quickly, sublinguals are a great alternative to inhaled methods.
Sublingual cannabis also mirrors inhaled methods (smoking, vaping) in how long it lasts. While the effects of edibles can last six to eight hours, sublinguals tend to only affect the user for two to three hours."
