schedule 1 drugs would be cocaine etc. Valium and Oxycontin are, I believe, schedule 2. Hydrocodone would be a schedule 3, but enough about that.
From my experience, my mother is a pharmacist in Nicaragua and owns her own pharmacy. In these countries not everyone can afford to pay for doctor's visits. The majority of the population barely make enough for the essentials. So, pharmacies try to help these individuals by paying a doctor to sign off on these prescriptions once they make a sale. Before the pharmacy is able to restock the supplies, the pharmaceutical companies requires them to have the prescription signed by the doctor to get X amount of the drug to replenish stock. The amount the pharmacies pay the doctors is minimal. Yes, there is liability involved for the doctor but they are willing to take that chance. In Nicaragua is not unheard to have a Doctor driving a taxi just because he/she does not have the right connections to get a job out of school. Medical school is free or very cheap. But in return, One has to have 1 to 2 years of community service (servio social) in very poverty sticken locales. It is during these two years that doctors get their experience before they can go on their own.
The economy is not as it is here. I wish I could sit here and discuss it but we'll save that conversation for one night over some scotch. Also, understand that addiction from prescription drugs is very low in these countries for the lack of fundings by the individuals. You mentioned ******, ******, and Levitra. Well, you must know that in these countries there is alot of machismo involved. Their performance is something that is very valuable to males. I would not be surprise to find out that a man did not eat for a day in order to buy one of those pills. Again, Sex everyday is very rare, so there is no chance that they will starve to death by missing a meal here and there
Also, the drugs you find in this countries can be manufactured in the USA, Mexico, Germany, etc. However, it all deals with the policies in those countries. With Ortega coming back to power in Nicaragua, he wants to stop all the imported drugs an sell only the drugs manufactured in Nicaragua. These drugs tend to be of lesser qualities for they do not have to follow FDA approval. You can get your doctor to write you a RX for three months and get it through a mail-in-service and you only pay one copay and have three months of meds. There are also certain pharmaceutical companies that offer rebates on their medications. You just have to get a card from that company and see which medicines apply. I hope this gives you a little insight. Sorry that this went so long. happy sailings.
