It could be happening to me. No texting, twiter and facebook but I cannot stop searching for related subjects to marijuana, everything related to it. While at work I spend 6 out of 8 hours googleing the shot out of the iphone and home a bit to. Don't get me wrong, is not that I do it instead of working just that my work is sitting on a chair and hitting some clicks... Gotta make the time pass somehow and dopamine helps lol.
