Just a question:
Does smoking or cigarette smoke lessen the effectiveness of the pheromones?
Yes. Less healthy people have duller senses and are less responsive to olfactory signals. Of course the reduction of effectiveness varies according to the individual and their physical condition. Someone whom smokes a couple packs daily probably doesn’t give rat’s tail about a healthy lifestyle nor have much energy for a sexual or social life. A weekend toker probably will see little or no reduction.
