如何用一两段话回答这个有关ethics的英语问题?

Purchasing medication over the Internet might seem convinient,but it can cause a lot of problems.
Some prescribed medicine is only available to those who have their doctors' prescription for a reason.Certain side effects of such medicine might be mild,but others might cause severe problems,or may even be fatal if used improperly.Also,some types of prescribed medicine have small amounts of drug contents that are not substantial enough to cause major damage.However,overdose of such medication may cause severe damage to the brain or even death.
Therefore,purchasing medication online without a doctor's prescription is extremely unsafe for patients and thus should be prohibited by law.
