Experienced Marijuana Users May Be Sensitized to the Effects of the Drug

Experienced marijuana users may be sensitized to the effects of the drug for all of the following reasons,EXCEPT:

A) THC accumulates in the fat tissue of regular users; smoking more marijuana liberates the remaining THC producing a quicker "high."
B) CB1 receptors are upregulated in regular users.
C) An awareness to the subjective effects of the drug must be developed in novice users-regular users know what to expect.
D) Regular users know how to smoke marijuana to get a sufficient dose of THC-new users have to learn this process.
