Drug addiction has attached itself to the society as an indelible stigma, so to say. What is then drug addiction? How do the drug addicts feel when deprived of their elements of addiction? A drug addiction is a strong longing for taking a drug that makes you descend into a world of feel-good. For instance, inhaling cocaine turns you energetic, cautious, euphoric, with heightened mental agility. If you happen to be deep into addiction, abstaining from drugs that you’re used to becomes a nightmare. For instance, remaining deprived of cocaine can trigger agitation, depression, extreme fatigue, anxiety, angry outbursts, lack of motivation, vomiting, shaking, irritability, muscle pain, and interrupted sleep. Abstention from drugs more often than not throws your psychic balance into disarray. You simply go nuts over the absence of your drug when you feel an irresistible urge to take it.
