Hello. Not sure if its ok to ask something like this, but i would like to know which opiates/opioids can be smoked for possible dose reduction instead of taking them orally ? I know hydromorphone and morphine base can be...but what about regular pills and other related chemicals like codeine, hydrocodone, dihydrocodeine, oxycodone, oxymorphone, tramadol, tapentadol etc. Thanks for info.
