Where are CB2 receptors primarily located? 
CB2 receptors are primarily located throughout the immune system. For example, they are found in the tonsils, spleen, and on various immune cells, including lymphocytes, natural killer (NK) cells, monocytes, macrophages, mast cells, and microglia. CB2 receptors are also expressed outside the immune system in the gastrointestinal tract, hematopoietic cells, bone, keratinocytes, reproductive tissues, and the cardiovascular system. The expression of CB2 receptors is relatively low under normal conditions but in states of neuroinflammation and neurodegeneration, the expression of CB2 receptors is upregulated.

What are the onset, intensity, and duration of effects of swallowed cannabis?
There is significant interindividual variability in the onset, intensity, and duration of effects of orally consumed (and swallowed) cannabis. Grotenhermen reported that the psychoactive and physiological effects of orally consumed cannabis appear about 90 minutes after ingestion, reach their maximum within 2-3 hours, and last for 4-12 hours. Zamarripa and colleagues found slightly different results; the effects of orally consumed THC peak between 1-5 hours after ingestion and last for ~ 6-12 hours. Grotenhermen, F. (2003).

Are CB-1 and CB-2 the only receptors with which cannabinoids interact?
No. In addition to interacting with CB-1 and CB-2 receptors, some endocannabinoids and some cannabis-derived compounds also interact with other targets, including transient receptor potential vanilloid-1 (TRPV1) channels, G-protein-coupled receptor 55 (GPR55), and peroxisome proliferator-activated receptors (PPARs).

Compare the efficiency of vaporizing cannabis to that of smoking cannabis.
Vaporization, as compared to smoking, is generally more efficient at delivering cannabinoids. When vaporizing, consumers absorb approximately 33% of available cannabinoids compared with about 25% during smoking. This greater efficiency is due to reduced thermal degradation of THC and a decrease in side stream loss. Peters, J., & Chien, J. (2018). Contemporary routes of cannabis consumption: A primer for clinicians. Journal of the American Osteopathic Association, 118(2), 67-70. https://doi.org/10.7556/jaoa.2018.020

Compare the safety profile of vaporizing cannabis to that of smoking cannabis.
Unlike smoking, which involves combustion, vaporization heats the cannabis flower or extracts to temperatures high enough to volatilize cannabinoids into an aerosol but below the temperature at which cannabinoids combust. As a result, individuals who vaporize cannabinoids are not exposed to the toxic by-products of smoke, such as carbon monoxide and tar.Zamarripa, C. A., Vandrey, R., & Spindle, T. R. (2022).
