What happen to people's body when they takes drugs?

Answer 1

I suppose it will depend on which drugs you take, but the most common non-pharmaceutical drugs:

Marijuana:

• Rapid heart rate
• Increased blood pressure
• Increased rate of breathing
• Red eyes
• Dry mouth
• Increased appetite, or "the munchies"
• Slowed reaction time

Cocaine:

• an increasing sense of energy and alertness
• an extremely elevated mood
• a feeling of supremacy

On the other hand, some people describe other feelings tagging along with the high:

• irritability
• paranoia
• restlessness
• anxiety

• dilated pupils
• high levels of energy and activity
• excited, exuberant speech

Cocaine's immediate effects wear off in 30 minutes to two hours. Smoking or injecting cocaine results in a faster and shorter high, compared to snorting coke.

Heroin:

• Shortness of breath
• Dry mouth
• Constricted (small) pupils
• Sudden changes in behavior or actions
• Disorientation
• Cycles of hyper alertness followed by suddenly nodding off
• Droopy appearance, as if extremities are heavy

• Behavioral signs of heroin abuse and addiction include:

• • Lying or other deceptive behavior
  • Avoiding eye contact, or distant field of vision
  • Substantial increases in time spent sleeping
  • Increase in slurred, garbled or incoherent speech
  • Sudden worsening of performance in school or work, including expulsion or loss of jobs
  • Decreasing attention to hygiene and physical appearance
  • Loss of motivation and apathy toward future goals
  • Withdrawal from friends and family, instead spending time with new friends with no natural tie
  • Lack of interest in hobbies and favorite activities
  • Repeatedly stealing or borrowing money from loved ones, or unexplained absence of valuables
  • Hostile behaviors toward loved ones, including blaming them for withdrawal or broken commitments
  • Regular comments indicating a decline in self esteem or worsening body image
  • Wearing long pants or long sleeves to hide needle marks, even in very warm weather
  • Weight loss
  • Runny nose (not explained by other illness or medical condition)
  • Needle track marks visible on arms
  • Infections or abscesses at injection site
  • For women, loss of menstrual cycle (amenorrhea)
  • Cuts, bruises or scabs from skin picking

LSD:

• Dilated pupils
• Higher or lower body temperature
• Sweating or chills ("goose bumps")
• Loss of appetite
• Sleeplessness
• Dry mouth
• Tremors
• Delusions
• Visual hallucinations
• An artificial sense of euphoria or certainty
• Distortion of one's sense of time and identity
• Impaired depth perception
• Impaired time perception, distorted perception of the size and shape of objects, movements, color, sounds, touch and the user's own body image
• Severe, terrifying thoughts and feelings
• Fear of losing control
• Panic attacks
• Flashbacks, or a recurrence of the LSD trip, often without warning long after taking LSD
• Severe depression or psychosis

In other words, best not to do any of these. Good luck.
