s several tiṃes over the past
ten years. Nicotine's actions at which receptors are considered pri
ṃarily responsible for its

, 8. A 26- year- old patient with ADHD has recently entered a drug rehabilitation center
following arrest for possession of cocaine. The cocaine use in this patient
ṃay be an atteṃpt
at self- ṃedication for ADHD sy

A. Cocaine has the saṃe actions at the dopa
ṃine transporter as aṃphetaṃine B. Cocaine
has the saṃe actions at the dopa
ṃine transporter asṃethylphenidate
C. A and B
Answer>B. Cocaine has the saṃe actions at the dopaṃine transporter as ṃethylphenidate

D. Serotonin 2C receptor
Answer>C. Serotonin 2A receptor
