Explanation:
Drugs have different effects depending on the drug itself, the person taking it and their surroundings. Taking drugs can affect not just your physical and mental health, but your whole life. Just one pill can kill.
Each drug causes different physical reactions, depending on the type of drug. Some will make you feel more awake, alert and energetic. Others will give you a calm, relaxed feeling. Some alter your perceptions and can cause hallucinations. Others may make you feel numb.
Long-term use and larger doses have negative effects that can seriously harm your health, even cause death, including disease risks from sharing needles, and permanent damage to the brain and other organs.
1.Absorption:-
When you use a drug it is absorbed into your bloodstream. How quickly this happens depends on how you took the drug.
2.Distribution:-
Once a drug is in your bloodstream it circulates through your body, being distributed to different organs and the brain. The drug affects chemicals and receptors within the brain, causing different effects depending on the type of drug.
3.Metabolism:-
Your body then metabolises the drug or breaks it down into simpler molecules (known as metabolites) which can be more easily eliminated. Sometimes these metabolites can also affect your body.
4.Excretion:-
Metabolised drugs go through your digestive system and exit your body, usually in urine or faeces.
