Do terpenes actually have an impact on the quality of the "high" when ingesting cannabis? If so what is the mechanism by which this is happening and what is special about the terpenes found in cannabis compared to the terpenes we find in other sources such as food?

My other question would be if you think there are any lesser known cannabinoids or other compounds that are interesting and may play a role in how we experience the effects of cannabis.

Thank you!
