While some people may already be aware of signs of addictions, you may not be aware of the “psychological” signs of addiction because they are so close to so many other problems that are out there. Some of the psychological signs of addiction are people that seem to have trouble keeping their train of thought together. They may seem a bit lost in thought or with no thought at all. Now this could easily be mistaken for other mental problems, but the key to telling the difference is that the person will often make a reference to the fact that they actually need the drugs or the alcohol to get their mind straight or maybe even to be able to think. Now this is not to say that someone could have the same signs and “not” make a reference to the alcohol and the drugs. You pretty much have to be very tentative to the signals you are getting from a person.
