Are there any tests comparing the efficacy of cannabis delivery methods?


Yes there have been studies performed comparing efficacy across the different routes of administration. However, there are several variables that make it hard to determine efficacy including:

  1. Variation among cannabis products
  2. Cannabis drug interactions
  3. Difference in cannabis metabolism among individuals
  4. Uniform dosing
  5. Limited human cannabis studies

Here is an article below that discusses differences among smoking, oral, oromucosal, rectal, and topical ingestion of cannabis.
