وبدأت وأنا عمري 16 سنة في تدخين الحشيش وشرب الخمر لأول مرة وذلك أيضًا بدافع المغامرة و حبي للتجربة و الشعور بالاختلاف. تصورت في هذا الوقت أن لا أحد يستطيع أن يفعل مثلي، فكنت ألتقي مع أصدقائي في كل يوم خميس ليلاً لكي ندخن الحشيش ونشرب الخمر ونضحك ونتحدث. استمر هذا الحال سنوات قليلة وكانت شكوك أهلي كثيرة تجاهي بسبب كثرة سهري خارج المنزل والأحاديث السرية في التليفون وأموري الغريبة. ولكني كنت أنجح في الدراسة لذلك لم يستطيعوا مواجهتي بالتقصير أو الإهمال. في ذلك الوقت كنت أنجح في الدراسة عن طريق الغش والتزوير.
Nicotine also is absorbed readily when tobacco is chewed. With regular use of tobacco, levels of nicotine accumulate in the body during the day and persist overnight. Thus, daily smokers or chewers are exposed to the effects of nicotine for 24 hours each day. Nicotine taken in by cigarette or cigar smoking takes only seconds to reach the brain but has a direct effect on the body for up to 30 minutes.

Addiction to nicotine results in withdrawal symptoms when a person tries to stop smoking. For example, a study found that when chronic smokers were deprived of cigarettes for 24 hours, they had increased anger, hostility, and aggression, and loss of social cooperation. Persons suffering from withdrawal also take longer to regain emotional equilibrium following stress. During periods of abstinence and/or craving, smokers have shown impairment across a wide range of psychomotor and cognitive functions, such as language comprehension.
The central nervous system (CNS) actions that result from taking even small amounts of methamphetamine include increased wakefulness, increased physical activity, decreased appetite, increased respiration, hyperthermia, and euphoria.

Magic mushrooms are normally consumed orally (ie. eaten) either raw or dried out. Raw magic mushrooms are about 90% water. Amanita muscaria is not often eaten raw as the user can experience severe nausea. Magic mushrooms may also be cooked or combined in food dishes though heating generally breaks down the psychoactive substance. 1 to 5 grams are normally consumed.
