What are the best pain killers to use?
 

Which pain killer medicine has the least side effects?

It depends on the pain, what kind of pain do you experience? For example, CBD is the best and effective pain relief. It also helps to get rid of chronic pains. If you decide to buy it, make sure you are choosing the most potent CBD products.

Good thread discussion, and thank you so much for sharing it.

I think, only a doctor or a pharmacist can answer this question. If you want to find it out, choose the most popular pain killers, check the info about them on the Canada Drugs site, and compare which one has the least side effects. Hope it helps!
