People often underestimate how difficult it is to get medicines in other countries. You can buy over-the-counter drugs but you can't be 100 percent sure you have the right thing. They could be the wrong medication or the dosage may not be the same.

It depends on where you go. But it's reasonable to take precautions because you can get a lot of (health related) things while traveling.

There's only so much you can do. Are you not going to do something because of political unrest? You have to balance the risk and the benefits.

There's a bottleneck getting drugs to people and we may now be able to test thousands of compounds that would not have been evaluated under the prior method.

People should be closely monitored, but not because these drugs are especially risky. The real problem in the treatment of depression is that people start medicine and the medicine has side effects or the medicine doesn't work right away, and they get discouraged and they drop out.

We believe that some people should get their drugs for free, and a small class of people should even be paid to take them.
