The study adopted a feasibility mixed methods approach. The ITASUD was implemented with 39 male users of cocaine/crack as their principal drug with high levels of anxiety. The outcome (anxiety) was assessed by the Beck anxiety inventory. To address the feasibility criteria, data were gathered during appointments. Additionally, qualitative open-ended interviews were conducted in the final appointment. The assessment of the six feasibility criteria indicated the following: (1) demand: there was high demand among eligible participants; (2) acceptability: the ITASUD had better acceptability until the 3rd appointment; (3) implementation: the ITASUD’s complexity and design was acceptable for participants; (4) practicality: 61.54% of participants used strategies from the ITASUD to manage their anxiety; (5) adaptation: there was no contamination and cointervention; and (6) safety: the ITASUD was safe. The exploratory analysis showed a relation between the level of anxiety and ITASUD (p < 0.0001). The ITASUD appears to be feasible. The participants reported positive experiences with the implementation of the ITASUD. The findings support the design of a powered larger trial to evaluate the effectiveness of the ITASUD.
