A 12-week treatment with dulaglutide (1.5 mg weekly) does not improve long-term smoking abstinence rates compared to placebo when used as an adjunct to standard cessation therapy.

If you are trying to quit smoking, taking dulaglutide (Trulicity) alongside standard treatment (like Chantix/varenicline) will not increase your chances of staying smoke-free compared to standard treatment alone. Do not expect dulaglutide to help you quit smoking.

Dulaglutide does not improve long-term smoking abstinence... The point prevalence abstinence rates declined from almost two thirds of all participants at week 12 to 43% (54/127) in the dulaglutide and 41% (52/128) in the placebo group at week 24 and to 32% (41/127) and 32% (41/128) at 52, respectively.
