Drug companies spend many millions of dollars promoting ED medications. I’m sure they realize that most of the persons using these medications are using them as a prescription recreational drug, not as a treatment for a valid disorder.
What they have found is a way to make large profits promoting medicines to people who are not ill. If you find a drug that treats or cures an illness, only those persons with that illness will buy the drug; your market is limited. But if you can find a drug that has two uses, the treatment of a medical disorder and a recreational drug, you can market that drug cleverly for recreational purposes, and sell it again and again to persons who are well. The market for the drug is increased many fold, and so are the profits. I expect that this trend in pharmaceuticals will only increase over time. I expect that pharmaceutical companies will actively search for these types of recreational drugs, so as to bring them to market on the excuse of treating a disorder.
The same type of process occurred with oral contraceptives. Originally, they were available only for treatment of certain medical disorders. But women would claim to have this type of disorder so as to obtain the contraceptive effect. And physicians and drug companies were not, I think, unaware of this trend. The number of women claiming to have such a disorder, which supposedly required oral contraceptives to treat, rose sharply. This was followed by the legalization of contraceptives (which formerly, in the U.S. were not legal). I believe, in accord with the teaching of the Catholic Faith against abortion, that not only all direct abortions, but also all abortifacient contraceptives, should be illegal to prescribe or to use.
In a sense, oral contraceptives are a type of prescription recreational drug, because they are so often used in order to obtain the pleasure of sex without the consequence of procreation.
In California, medical marijuana has become a prescription recreational drug. Some small percentage of the population, those with grave illnesses, can benefit from medical marijuana. It is not immoral for such persons to use marijuana to treat a serious medical disorder. However, the vast majority of ‘prescriptions’ for medical marijuana are given out on the basis of a claimed minor medical problem, such as stress, or sleeplessness, or loss of appetite, etc. Anyone might make such a claim, without any basis in medical fact, thereby obtaining a prescription for marijuana as a recreational drug.
The result is that companies can make large profits selling drugs for recreational use on the basis of a false claim that the drug is treating a medical disorder. And even when it becomes widely known that this is the case, the laws and customs do not change. Everyone realizes that a lie is being used to make a recreational drug legal, and few persons object.
