Without knowing the exact ingredients and ensuring that they are put under extensive research there is no way to know the long term effects on anything like this. I know however that Androtics put a lot of love and care into their products, even ordering high quality organic ingredients over cheaper alternatives so I’m sure they would do their best to avoid anything dangerous.
On the other side of the equation, I along with the majority of people I know continue to drink alcohol when we know it damages our liver and many others will smoke daily which is known to cause cancer. I even read a theory in a tabloid once that bacon can cause cancer. At the end of the day we live in both a time and society where there are potential hazards on every corner, both man made and otherwise so unless something is overtly causing you harm or has an unusually high risk then I see no need to worry.
As a further note another article I saw mentioned that these packaged sandwhiches you can buy often have chemical ingredients which left even a single day past it’s date can become hazardous. Now I don’t know about your opinion but I’m sure those chemicals aren’t sitting there watching the clock and we eat this stuff!
EDIT: Looks like this has already been discussed as well - Long term health effects of pheromones?
