The active substance in cannabis, THC (Delta-9-tetrahydrocannabinol), affects brain neurons and their receptors, which impacts concentration, memory, cognitive functions, coordination, and changes in behavior control.

Marijuana use disrupts mental well-being.

Signs of addiction include:

  • Increased tolerance, inability to achieve the usual high
  • Irresistible craving
  • Long time spent obtaining and using the drug
  • Continuous use despite problems created
  • Difficulties in fulfilling responsibilities (interpersonal relationships, academic performance, job responsibilities), which contributes to self-critical thoughts and anxiety
  • Decreased self-esteem
  • Unsuccessful attempts to quit use independently

Withdrawal symptoms include:

  • Irritability
  • Anxiety
  • Sleep disturbances
  • Mood swings
  • Reduced enthusiasm and energy
  • Paranoia
  • Psychosis
  • Exacerbation of neurotic conditions

Along with the desire to overcome addiction, maintaining a stable mental state and minimizing factors leading to relapse are essential.
