The correct answer is B. Experience conditioning in her brain that will cause cravings

Explanation:

The use of drugs has important effects on the body; in the case of marijuana it has been found, this changes the levels of dopamine that is the hormone responsible for the satisfaction or pleasure feeling. In this way, marijuana makes users feel pleasure and this leads to conditioning, which means the individual craves the drug because this makes him/her feel good.
