Drugs most commonly consumed through the method of sniffing are cocaine and crack. These highly addictive substances are cause for alarm in family members and friends of the drug abuser. They will alter the mood and emotions of the addicted person and can cause strain on relationships. It is important to know the signs of someone that is sniffing drugs in order to intervene and help him move forward in life.
Someone who uses cocaine a lot will exhibit extreme energy, especially after he has just used the drug. He will become talkative and appear very focused and alert. This also depends on how quickly and easily the cocaine is absorbed into his system. The stronger the dose, the more energetic he will appear. If this is not typical of the person, this is a sign that he could be sniffing drugs.
As the drug abuser continues sniffing drugs over time, she will appear moody. The euphoric, energetic feeling she has when she first take the drugs will begin to wear off, causing her to feel irritable and grumpy. This is why you will notice unusual mood swings in the person. When the drug is first used, it releases chemical mood enhancers, such as serotonin, but as the person's high begins to fade, the chemical goes with it, causing the person to feel depressed or "down."
Decrease in Appetite
As sniffing drugs reduces energy levels, his appetite will decrease. This is sometimes temporary and comes with the high but if the person is using drugs enough, the weight loss could also be potentially harmful. If you have suspicions of someone abusing drugs, watch to see if he is eating normally or losing weight, along with watching for other possible signs.
If you notice that your loved one is having recurrent life issues, she may be sniffing drugs. For example, if she is having multiple legal issues, getting involved in crime, irresponsibility at her workplace, or difficulty in relationships, a drug addiction could be the foundational problem to these issues. Take note of behavior that isn't consistent with the person normally.
