The second-hand smoke is a phenomenon that needs to be investigated, and its effects on the health of the people are to be
examined. To analyze such an issue, the mathematical models are the best tools that help us to study the dynamical behaviors
of this phenomenon. For this purpose, in the present paper, we consider a three-compartmental fractal-fractional mathematical
model of a specific population of smokers or people that are exposed to second-hand smoke. By assuming some conditions on
ϕ-ψ-contractions and compact operators, we prove some theorems in relation to the existence of solutions. The Banach
principle for the usual contractions is used for proving the uniqueness of solutions. Next, by some notions of functional
analysis, two types of Ulam-Hyers stability for the fractal-fractional second-hand smoker model are established. Moreover, we
have a steady-state analysis and obtain equilibrium points and basic reproduction number R0. Then, we investigate the
sensitivity of the fractal-fractional system with respect to each parameter. For numerical simulation, the Adams-Bashforth (AB)
method is used to derive numerical schemes for plotting and simulating the approximate solutions. Finally, the obtained
solutions are tested with real data and different values of fractal dimensions and fractional orders.
