o o Acidification of urine – o o Stressful Conditions – Neurochemical Effects  Activates nicotinic cholinergic receptors  stimulation of dopamine release  Level of dop activity in system positively correlated to euphoria and reward o Nicotine is rewarding  increases dopamine levels  Modulatory action of GABA towards dopamine interference o GABA inhibits release of dopamine if over activity o Nicotine prevents negative feedback action of GABA  even more dopaminergic activation Nicotine Content  Typical 0.5-2.0 mg  Players 1.5  DuMauriers 1.1  Export A 1.7  Marlboro 1.0  Virginia Slims 1.1  20% nicotine content inhaled and reaches bloodstream  20/day – 4 mg/day  LD50 – 60 mg – typical cigar contains 2 Smoking Topography  Cigarettes smoked by machine – allows for consistency  Constituent levels on pack mimic smoking topography of smoking machine o Depth and volume of inhalation o Amount of time smoke is held in lungs o Holes in filter covered/uncovered  Light cigarettes – filters have small holes to dilute smoke o Less satisfying  inadvertently or on purpose cover holes  more constituents inhaled Constituents – over 4000 compounds  Tar – any substance in smoke other than nicotine and carbon monoxide o Filter – brown: tar, darker: more tar inhaled than smoke o Paralyze cilia in lungs allowing constituents to remain in lungs  Carbon Monoxide – binds to hemoglobin  carbonhemoglobin – reduces oxygen carrying capacity of blood o Smokers have 10x Physiological Effects  Brain stem vomiting center  Increased heart rate and blood pressure  Constricts blood vessels  cold, clamy hands and feet Psychological Effects  Cholinergic nervous system  Nicotine o Enhances performance in task requiring concentration over long time period o Reduces interference from irrelevant stimuli and increase attention to relevant stimuli o Stroop Task – name colour which word is printed  Nicotine faster than no nicotine  Alzheimers – cholinergic hypofunctioning o Nicotine helps alleviate cognitive deficits o Activation of system beneficial  Animal Models – ameliorate learning and memory deficits in aged animals Self Administration and CPP  Progressive ratio procedure in dogs – BP=500  Support CPP  Drugs blocking acquisition an/or expression of both o Mecamylamine – blocks nicotine receptors o Rimonabant – blocks canaboid receptors Tolerance and Physical Dependence  Inconsistent evidence concerning tolerance o Some mood effects, little performance effect o Animals – little tolerance locomotor, reinforcing and dopamine release o Tolerance plays little role in addiction  Clear evidence for withdrawal and physical dependence o Animals – teeth chattering, abdominal writing, gasps and chews, o Humans DSM – decrease in arousal, sleep disturbances, irritability, attentional deficits, restlessness, headaches, increased appetite o Symptoms last 10 -30 days Treatment  Nine failed attempts before successfully quitting  Relapse rate 95%  Increased likelihood of abstinence – older, male, married, smoking fewer cigarettes, having a lower addiction level, having smoked for fewer years, more previous quitting attempts, high efficacy  Women smoke less for nicotine – fewer cigarettes/day, lower nicotine, inhale less deeply – should make less dependent o Sensory effects, conditional cues, social pleasures Pharmacotherapies Name Active ingredient How it Works Implications Nicotine Tansdermal patch/ -Maintaining -Smokers still want replacement chewing gum nicotine blood cigarette levels other than -Not only factors in smoking reduces smoking withdrawal - Not super symptoms successful - nicotine level - Reinforcing gradually reduced effects not soley due to nicotine Sustained Release Burpropion - If used with NR, Bupropion Nicotinic receptor better than either (success double antagonist and alone than that with block dopamine placebo) reuptake Champix Varencline – - Occupies nicotinic - Reduces both partial receptor receptor  cannot withdrawal and agonist at nicotinic be occupied by cravings receptors nicotine  - May produce reduced level of psychiatric effects nicotinic stimulation  reduced dopamine release Smoking in Pregnant Women  Spontaneous abortion and still birth, premature birth, low birth weight, and strabismus  Animals – increased activity, decreased learning and memory in a variety of tasks, changes in brain and neurochemical functioning  Humans – developmental delays in math, reading and general intellectual markers, externalizing behaviour, reduced intellectual abilities, ADHD  Deficits more pronounced, more cigarettes smoked (10+/day) – clear  Effects due to o Direct action of nicotine on fetus o Indirect result vasoconstriction – reduced uterin blood flow o Increased cellular hypoxia  Father smoking – smoking depletes vitamin C sperm abnormal Cannabis  Sativa, indica, or ruderalis  Cannabinoids – several hundred chemical agents, 60-80 unique to plant  Hot, dry climate – fiber content weak, so much resin – covered in dew  Cold, humid climate – fiber content increases, resin production falls History  10,000 YA – fibers, oldest cultivated plant not for food  Middle East – ideal climate for high THC climate  France: JJ Moreau de tours – fencing with a bowl of fruit  Canada 1606 by British – hemp  Prohibition o “tea-rooms” – more common than speakeasies  US Law – Harry Anslinger – relentless campaign against drugs o Laws b/c racial minorities used it  negative attitudes toward drug o 1936 – laws prohibiting marijuana  Canada: Marijuana = narcotic THC  Isolated and synthesized – 1964  Typical joint weight o 1970 – 1.5 grams: 15-30 mg THC o 2013 – 60 mg THC  Total harvested – 2.5 billion  Ounce = $250-200 Hashish  Dried resin of flowers and leaves of plant  THC content – 10%  Preparation o Boiled in solvent (alcohol) – extracts cannabinols o THC content - 40%  Europe 1800s – British colonization of India and Napolean’s expeditions  Le Club des Hachicins - Theophile Gautier o Hachicins – leading literary and art figures of the time o Dawamesc – sweetmeat – flower tops boiled in butter, strained and seasoned Method and Absorption  Bong/ Hookah –pipe-like devices in which smoke passed though water prior to inhalation  Blunt – Marijuana tobacco mixture packed into a hallowed out cigar  Less than 50% of THC in joint available for absorption, considerably less actually absorbed o Actual amount 5-10 mg  Smoking efficient getting drug to brain  Seconds – onset of effects  10 minutes – peak bloo
