A symptom is something the patient senses and depicts, while a sign is something other individuals, for example, the specialist take notice of. Example is the case of dilated pupils being a sign while constant sleepiness is a symptom.
Substance dependence is when someone is addicted to a something like drugs or alcohol and they are not able to control their use of the substance. He/she continues to use it, despite the fact that it may be harmful (the person may or may not be aware of the possible risk).
Being dependant on a substance can lead to strong cravings. It will be extremely difficult for the addict to stop using the substance without external assistance, even when they want to.
The symptoms and signs of drug addiction differ according to the person, the drug they are dependent to, their genetics (family history) and personal situations.
The clues and indicators of addiction could be that:
Unsuccessful attempts at stopping - the person taking the substance, like nicotine, alcohol, or other drugs, has made at least on serious try at stopping and was unable to.
Reactions when trying to stop taking the drug, when the body has less of the substance than it is used to, it reacts, and the person can have physical pains and altered moods. Some of these symptoms include cravings, moodiness, lack of focus, depression, frustration, anger, or resentment.
The person's appetite may suddenly go high. A sleeping disorder is a typical side effect of withdrawal. Constant vomiting and constipation may also occur in some situations. Depending on the drug, some will cause the person to be aggression, shivering, convulsions, delusions and perspirations.
Even with the knowledge that health problems exist, addiction continues - The person keeps taking the substance on a regular basis, even though negative health problems are becoming apparent. For instance, a smoker may keep smoking even after a lung or heart condition prevails.
Social sacrifices happen as activities are given up because of the addiction. A drunkard might choose not to go camping or boat ride if there will not be alcohol or a smoker might choose not to join his friends if they are meeting in a no-smoke pub or hotel.
Keeping a good reserve - addicts will at all times ensure that they have a good reserve of the substance, even when they do not have a lot of cash. Sacrifices might be made in other parts of their budget so they can make sure they always have their substance of choice.
Risky behaviours (1) - users will take unnecessary risks to make sure they can get the substance, like stealing or trading sex for money or drugs.
Dangers of Addiction (2) - When the addict is on the drug, they may take bold actions like over speeding.
Coping with problems - an addict often feels like they cannot deal with their problems unless they are using.
Obsession - a dependent individual may invest increasingly time and energy concentrating on methods for getting hold of their substance and sometimes how to utilise it.
Serenely and isolation - much of the time the addict may take their substance alone and even in mystery.
Forswearing - a critical number of individuals who are dependent on a substance are trying to claim ignorance. They don't know (or decline to recognise) that they have an issue.
Excess consumption - the individual takes too much of drugs, nicotine or alcohol in some cases of addiction. Some noticeable health symptoms like persistent cough, sore throat and blackouts that erase part of their memory could be the case.
Dropping diversions and exercises - as the compulsion advances the individual may quit doing things he/she used to appreciate a considerable measure. This might even be the situation with a smoker who finds he/she can't physically deal with participating in his/her best-loved sport.
Stashing the substance - an addict might hide small stocks of the substance in unlikely places, like around the house or in the car.
Binging - Taking a lot of the substance at the beginning. The addict will usually take a lot of the substance quickly so that they get the effect fast.
Having problems with the law - many of the drug and alcohol addicts(except nicotine) suffer this problem. This might be either on the grounds that the substance disables judgment and the individual goes for broke they would not take in the event that they were calm or with a specific end goal to get hold of the substance they overstep the law.
Money problems - if the drug is costly, the addicted person may neglect or cut down on other needs to afford it. In some countries, even cigarettes are very expensive, like in the UK, UK, and parts of Europe where someone who smokes two packs a day will spend '660 per month, nearly '8,000 per year.
Relationship troubles - drug and alcohol addictions can cause a lot of relationship problems.
Some substance/liquor abusers who are not actually dependent may likewise experience the ill effects of or cause a portion of the portrayals specified above, yet they don't more often than not have the withdrawal manifestations of someone who is addicted or a similar impulse to devour the substance.
