Since marijuana and Marinol derived from two entirely different processes (arguably polar opposites), it seems ironic that Marinol functions as the only legal alternative to marijuana. Considering their vastly disparate backgrounds, one can logically conclude that the therapeutic effects must also differ, but according to many researchers, the results are essentially the same. In fact, the two drugs' reported side effects are quite similar, although advocates of medical marijuana claim that Marinol produces more damaging side effects. Marinol proponents argue, in turn, that marijuana possesses more undocumented side effects. Upon analyzing a 1995 product brochure explaining the benefits and possible effects of using Marinol, I discovered new information that completely undermined my original assumptions about Marinol.
Considering that Marinol is legal while marijuana is not, I assumed that Marinol would have far fewer side effects than those attributed to marijuana; however, this assumption and numerous others proved quite inaccurate. According to the 1995 product insert, Marinol may be habit forming, a condition commonly linked with cannabis. In addition, Marinol may cause the following side effects: feeling "high" (i.e. easy laughing, elation, and heightened awareness), abdominal pain, dizziness, confusion, depression, nightmares, speech difficulties, chills, sweating, and even psychological and physiological dependence.19 Some of these potential side effects seem quite serious for any legal pharmaceutical. Even less comforting, the 1992 product insert explains what to do in case of accidental overdose:
A potentially serious oral ingestion, if recent, should be managed with gut decontamination. In unconscious patients with a secure airway, instill activated charcoal via a nosagastric tube. A saline cathartic or sorbitol may be added to the first dose of activated charcoal. Patients experiencing depressive, hallucinatory or psychotic reactions should be placed in a quiet area and offered reassurance.20
Considering the enormous sales of Marinol, patients must desperately need medication to risk such potentially severe reactions. While marijuana may produce such side effects as: euphoria, laughter, anxiety, dry mouth, red eyes, sleepiness, clumsiness, increased appetite; these conditions pale in comparison to those attributed to Marinol. A 1985 edition of The Medical Letter listed the side effects of Marinol as "disorientation, depression, paranoia, hallucinations, and manic psychosis." A 1986 Marinol product insert explains that even patients on low doses of the drug may experience "a full-blown picture of psychosis;" this reference was conspicuously dropped from their later product inserts.21 Given the intensity of Marinol's side effects, marijuana appears less dangerous than its synthetic Schedule II counterpart.
Many patients believe that the much higher THC content in Marinol produces these more extreme side effects. Robert Randall, a glaucoma patient who currently receives a legal supply of marijuana from the government, describes his experiences with Marinol, "It was way too psychoactive. When I took Marinol, I found it anxiety-provoking and intense, like I had wandered into a short story by Flannery O'Connor." He further explains, "I talked to hundreds of AIDS patients, and only one preferred Marinol to marijuana. It's not just that marijuana helps them gain weight-it's that Marinol is so scary." Dr. Robert Gorter, a San Francisco AIDS expert, corroborated Randall's anecdotal conclusions in the Journal of the Physicians Association for AIDS where he stated, "Again and again patients have testified that they preferred marijuana above dronabinol [the scientific term for Marinol]..."22 Further evidence citing the potential dangers of Marinol exists in the 1995 Marinol product insert itself, which warns against giving dronabinol to children and to the elderly (although Unimed is currently in Phase III testing for approval of Marinol in the treatment of Alzheimer's patients) because of the drug's "psychoactive effects."23 It seems odd that Marinol supposedly functions better as a medicine than marijuana, a substance casually consumed by millions of Americans without such debilitating side effects.
Hoping to discover specific patient complaints against Marinol, and not just potential side effects or anecdotal information, I contacted the Food and Drug Administration (FDA) for more information on adverse effects caused by Marinol. I was told that this information was confidential, and that only by using the Freedom of Information Act (and enclosing a check for $70) could I attain limited access to this knowledge, and even then, certain details would remain censored.24 By contrast, if I needed information on marijuana's adverse effects, I could contact hundreds of sources (including elected officials, rehabilitation centers, law enforcement, internet sites, parent groups, local libraries, pharmacies, etc.) from whom I could receive a deluge of free information. Another medical paradox exposing the sharp contrast between the popular conception of marijuana and Marinol involves carcinogenic studies. Anti-marijuana government studies had very tentatively linked marijuana smoke (and not ingested marijuana) with lung cancer in an unpublished report (although a recent panel of scientists re-examined that report and found that marijuana was actually found to prevent malignancies not cause them).25 Despite the presence of THC, common to both marijuana and Marinol, no carcinogenic studies have been performed on Marinol.26 Culturally, marijuana continues to face vilification while Marinol enjoys legitimacy and government backing. Sick people face harsh criminal penalties for self-medicating with natural THC, while patients using synthetic THC get insurance coverage and freedom from persecution and prosecution. The influential role that politics plays in science and medicine can explain the enormous rift in the cultural perception of these two essentially similar substances. Only a close examination of political influence in medicine can explain popular culture's polarity regarding marijuana and Marinol perception.
