Are marketing research studies, which sometimes include studies on cigarettes, forbidden or permissible, and what is the ruling on the transgressions committed therein, and is my work as an accountant affected by these studies?

It is not permissible for the company to conduct market research for forbidden goods, such as tobacco, because it aids in the spread of what is unlawful. Any research related to this must be rejected. It is permissible to give a reward to participants in surveys for permissible goods only.

It is not permissible for an employee to perform any work related to market research for a forbidden good, and he must refrain from doing so. If the company cannot allow him to limit himself to permissible work, then he must seek other employment.

If it is permissible for him to remain with the company, he should advise the company and explain the error of what the "recruiter" is doing, unless reporting him would result in significant harm. In that case, it is not obligatory for him, because duties are waived with a valid excuse.
