As we dicussed in your 23rd post regarding this matter"converting codine -morphine" D-E-M-E-T-H-Y-L-A-T-I-O-N is the answer.
As swiy is clearly not taking the advice that as been offerd on several occasions, i will at great risk of getting a serious nose flicking explain how somebody with a limited knowledge of chemistry may be able to achieve this.
CONVERSION OF {C18 H23 NO3} -{C17 H21 NO3} with limited skills....


To begin this sythesis the subject should be advised to oraly consume 75mg of dihydrocodine washed down with 150ml of boiled & distilled tap water,a waiting period of approx 3-4hrs should then be observed.
placing a 500ml pyrex collection jar at the tip of one`se meatus the donor should begin to collect the infused urine over a 8-9hr period.

The resulting urine would contain around [0.75mg dihydromorphine] and can be taken oraly.........TAKE THE HINT...........
