This may include suddenly missing more work than usual, losing interest in a career or failing grades in school subjects that would normally not be challenging to the person at all.While missing work or school can be a sign of drug use, sometimes spending too much time working can also be a sign there is drug use occurring. It is not unusual for some adults to start using drugs as a way to add more awake time to the day, so suddenly working nearly non-stop can point to a substance problem.
Friends at school or work may also change if there is a new drug problem. Your loved one may no longer want to see anyone socially due to fear of being caught. Or, they may have made new friends who share the same habit. If it is a change for your loved one to skip happy hour with co-workers not once but every week , this may mean there is something to hide.;
, Sudden changes in spending or missing money can be a sign of a problem they are trying to hide. Even small changes like not being quite as open as they have been in the past about money can mean there is something to hide like a drug or alcohol issue.Changes in money habits can also include a sudden use of credit cards or obtaining new lines of credit when that was not something they did in the past. Overdue bills are another sign that money is being spent on things that are out of the ordinary as well.
 Significant changes in both the physical body as well as mannerism may be a sign of drug use. Take a closer look at your loved one’s appearance. Is something different?Examples of physical changes may include losing weight, facial signs indicating lack of sleep, poor hygiene, and other changes like not keeping hair cut for work or being clean-shaven.
Depending on the drug of choice, they may also suddenly seem like they have endless energy and more movement due to “nervous energy”.
Beyond the physical body, you may also start to notice the same clothes being worn for a longer amount of time than usual. If the drug use includes the use of needles, you may also notice that they often wear long-sleeved clothing year round to hide the arms.
 Things disappearing at home may be a sign that property is being sold or traded for drugs, especially if the person has built up a tolerance to drugs. They may need more and more money to fund the drug use. This may include electronics or other items that are easily sold coming up missing.


Other signs of a problem may include family members noticing prescription drugs coming up missing like pain killers, attention meds or a variety of other drugs.Major changes in sleep patterns including either not sleeping for days on end or the reverse can mean drugs are in play. Certain drugs can cause one to stay awake for several days at a time and then cause a crash that sends one into days of sleeping.
