Zolpidem, a GABA-A receptor agonist and "Z-hypnotic" medication, has shown some efficacy in treating insomnia due to cannabis withdrawal, though there is a potential for misuse. Entacapone was well tolerated and decreased cannabis cravings in a trial on a small number of patients. Topiramate, an antiepileptic drug, has shown mixed results in adolescents, reducing the volume of cannabis consumption without significantly increasing abstinence, with somewhat poor tolerability. Gabapentin, an indirect GABA modulator, has shown some preliminary benefit for reducing cravings and cannabis use.The agonist substitution approach is one that draws upon the analogy of the success of nicotine replacement therapy for nicotine addiction. Dronabinol, which is synthetic THC, has shown benefit in reducing cravings and other symptoms of withdrawal, though without preventing relapse or promoting abstinence. Combination therapy with dronabinol and the alpha 2 adrenergic receptor agonist lofexidine have shown mixed results, with possible benefits towards reducing withdrawal symptoms. However, overall, the combination of dronabinol and lofexidine is likely not effective for the treatment of cannabis use disorder. Nabilone, a synthetic THC analogue, has shown benefits in reducing symptoms of withdrawal such as difficulty sleeping, and decreased overall cannabis use. Despite its psychoactive effects, the slower onset of action and longer duration of action of nabilone make it less likely to be abused than cannabis itself, which makes nabilone a promising harm reduction strategy for the treatment of cannabis use disorder. The combination of nabilone and zolpidem has been shown to decrease sleep-related and mood-related symptoms of cannabis withdrawal, in addition to decreasing cannabis use.
