Pointing out the difference between two fundamentally different chemicals which operate in different ways on different portions of the pain pathway is not showing off.

If you order a “Coke” and get Coke when you meant Root Beer, that is entirely different than asking for aspirin when you’re drunk and have a headache, getting Tylenol, and doing serious damage to your liver.

I suggest you work out why you’re so eager to accuse other people of showing off. Maybe it would be a good idea to fix it.

Was that really necessary? It sounds like you’re showing off. I’m a biochemistry major and was previously aware of the facts stated in your comment, but I didn’t personally feel the need to share them. Everyone refers to store-brand pain relief medicines by the blanket-term “aspirin.”

Are you going to draw the acetylsalicilic acid molecule for us next, then explain the synthesis of esters?
