I am very open-minded but what drugs is it referring to? Is it those illegal drugs because i sure am positive that it is not impossible since it is the bitcoin that matters and it doesn't state what are the things that are being bought using bitcoin as long as it is not referred to. It may even be possible that some officers of the government would even bust criminals with the help of bitcoins, it may even be possible to track the site where the suspect is using rather than where the bitcoin is going to for security even if the government is involved. On the other hand if it is actually referring to drugs to be used or bought from or to other countries it will be a really helpful payment since it is not just reliable but also fast, so payments for shipments from other countries will be earlier. And even in local use it is also more secure, for example you are going to buy medicine; a person can search a drug store with the available medecine needed and already pay for it so that the buyer would only pick it up and lessen bad guys to suspect you are carrying a huge amount or even little amount of money that will let them have the idea to rob you.
