^^ Well, thats supposed to be why they would be kept behind the counter. Frankly I think everything should be available to anyone, and if people die, well, tough fucking shit for them, there's too many humans on this planet as is, and they just keep poppin' more out like rabbits.
In reality, as its been said above, I really can't see any opiates, benzos, or amphetamines, or any kind of stiulants for that matter. A different kind of pain killer, gabapentin for example could be possible, and greatly useful for people who have severe pain or COX inhibitor sensitivity, though still unlikely. I cannot forsee any stimulants at all being allowed, unless the actually do schedule ephedrine and pseudoephedrine, and a different sympathomimetic may be made OTC or BTC for decongestion and asthma and such, phentermine, perhaps? Benzo's and other GABA agonists are very unlikely, but at least we still have nootropics like phenibut and picamilon, and herbals like kava and valerian.
The forces of corporate greed are just so categorically immense, and I would imagine that most pharms that would become available would be allowed only in brand names form, though possibly insulin could be BTC since it is so vital for so many, and has never been patented AFAIK. Think the recent OTC release of the fat blocking weight loss drug orlistat only available today OTC but only as Alli, commonly priced between $40-80, yet available in more rational countries at sometimes less than a fifth of that.
This is a positive move, but not nearly enough, at all. Its quite deplorable how we allow heartless corporations to pantent medicine.
