Nah, he'd just use is rectum.

Buspirone has no known potential for abuse, psychological or physical dependence[3]. Buspimen, Buspinol, Buspisal, Narol, Spitomin, Sorbon) is an anxiolytic agent and a serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. Its structure is unrelated to those of the benzodiazepines, but it has an efficacy comparable to diazepam in treating generalized anxiety disorder.[1][2] It shows no potential for addiction compared to other drugs commonly prescribed for anxiety, especially benzodiazepine medications. The development of tolerance has not been noticed. Cross-tolerance to benzodiazepines, barbiturates and alcohol does not exist. Furthermore, it is non-sedating. It is thought to act by interfering with the function of the neurotransmitter serotonin in the brain, particularly by serving as a 5-HT1A presynaptic receptor partial agonist. Additionally, it acts as a mixed agonist/antagonist on postsynaptic dopamine receptors. GABA-mediated effects are lacking. Buspirone may also have indirect effects on other neurotransmitters in the brain. The action of a single dose is much longer than the short halflife of 2-3 hours indicates. The bioavailability of buspirone is very low and variable due to extensive first pass metabolism. The drug is quickly resorbed. Taking the drug together with food may increase the bioavailability. The drug is highly (95%) plasma-bound. The active metabolite 1-PP is also a 5-HT1A partial agonist with anxiolytic properties, but weaker so than the mother-drug. It is also useful as an augmenting agent, for the treatment of depression, when added to SSRIs. The main disadvantage is that 1 to 3 weeks elapse before the anxiolytic activity becomes evident. Often patients have to be initially cotreated with a benzodiazepine for immediate anxiolysis. Generally, buspirone works less well than benzodiazepines. Therefore, benzodiazepines are often the first approach in immediately treating panic attacks and social phobias. It is also particularly difficult to treat patients pretreated with benzodiazepines knowing the immediate effects of these tranquilizers. Bristol-Myers Squibb gained FDA approval for Buspirone in 1986. The drug went generic in 2001.
