In the last few years, the number of people that consume tobacco and marijuana has increased, this increase is associated with mental health problems, cognitive and chronic preventable degenerative diseases (cancer, COPD, heart diseases, airway diseases).

A scoping review was conducted to identify evidence related to efficacy assessment, acceptance, and feasibility of the interventions addressed to dual users of tobacco and marijuana.

Material and Methods:
A literature search was conducted in the Scopus, PubMed, MEDLINE, and PsycINFO databases. Fourteen articles were included that evaluated the efficacy, acceptance, or feasibility of an intervention for dual users of tobacco and marijuana.

1) Different studies evaluate treatments aimed at dual users, which can be divided into the simultaneous or sequential application of treatments to leave a substance (tobacco or marijuana): in this regard, studies that applied multicomponent programs with cognitive behavioral techniques such as relapse prevention, contingency management, psychoeducation, self-control training, and motivational interviewing were identified, 2) It is noted that in the studies carried out, positive results related to feasibility and acceptance were obtained, however, abstinence rates are low in both tobacco and marijuana, mainly in the treatments applied simultaneously and sequentially. In some studies, consumption was reduced and attempts to quit smoking increased, lastly, it was given greater importance to complete treatment only for the use of marijuana but not tobacco.

It is concluded that it's indispensable to design and evaluate the feasibility, acceptance, and efficacy of an intervention aimed to dual users of tobacco and marijuana.
