I did not mean they are similar in compound - I meant in pain relief. Codeine has very few side effects whereas Tramadol has many.
If I take too much codeine I get all itchy and might even nod just like other REAL opiates.
I took too much tramadol once, I didn't feel very high (I certainly wasn't itching or nodding), and then I had my first ever seizure. Now I have the privilege of having a lowered seizure threshold for the rest of my life.
Now 1x 100mg dose of tramadol is enough to cause a seizure.
Forgive me for disagreeing with you, but you're wrong. So wrong. They're nothing alike. Not even close.
Kratom is a far superior opioid to tramadol.
There is a reason why codeine has been a controlled substance longer than I've been alive and tramadol wasn't even scheduled for years and years.
