The molecule tattoo can mean a generalized nod in the direction of the sciences, through to a very specific and personal relationship with a certain molecule. The beauty of a molecule tattoo is it allows you to say what you want to say without being in your face about it.
Most molecule tattoos are serotonin, dopamine and oxytocin – chemicals released by our bodies that make us feel good. If you’re really into other pastimes besides science then you can get the LSD or THC molecule. Either way molecule tattoos are going to have a specific meaning based on the molecule. This will be individual to the wearer.
