Overview - Stimulant Dependence and Psychosis

Description of Stimulant Dependence and Psychosis

Methamphetamines are potent chemical stimulants of the central nervous system (CNS). Illegal meth-labs produce and dealer networks sell the drug under names such as crystal meth, ice, or speed for instance. It is a common recreational substance used to induce stimulating, euphoric, or aphrodisiac-related effects. A pharmaceutical version (e.g. adderall) is prescribed to patients with ADHA or as a weight-loss drug. While methamphetamines can produce near instant stimulation, focus and excitement they can also cause a number of unwanted effects including neurotoxicity, addiction or psychosis for example. Methamphetamine is most commonly taken by ingestion, inhalation, or injection. Common emotional realities produced by the substance range between happiness, excitement, alertness, and focus on the expansive side and on the constricting side may include irritability, anxiety, paranoia, strange and violent/aggressive behaviors for example. Additional physical adverse effects include addiction potential, lack of appetite, increases in heart, blood pressure, and respiratory rate (increase risk of heart attack and stroke), increase in body temperature, twitching, bad teeth for instance.

Stimulant Dependence and Psychosis Symptoms:

Tachycardia, hypertension, moodswings (aggression to depression), psychosis, hallucinations (nightmarish), shaking (seizures), irregular heart rates, "crash and burn" as in extreme weakness and fatigue, hunger, craving for more stimulants (e.g. methamphetamine), photophobia

Drug Interactions

THC Interaction with Pharmaceutical Drugs

  • THC can enhance the effects of drugs that cause sedation and depress the central nervous system, such as benzodiazepines, barbiturates, and alcohol, for example. 
  • THC is metabolized by and an inhibitor of a number of enzymatic liver pathways referred to as cytochrome P450. There are more than 50 enzymes belonging to this enzyme family, a number of which are responsible for the breakdown of common drugs such as antidepressants (e.g. amitriptyline, doxepine, fluvoxamine), antipsychotics (haloperidol, clozapine, stelazine), beta-blockers (e.g. propranolol), bronchodilators (e.g. theophylline), or bloodthinners (e.g. warfarin).  Thus patients taking these classes of medication may find that THC increases the concentration and effects of these drugs as well as the duration of their effects.
  • Clinical observation suggests no likely interactions with other pharmaceuticals at a total daily dose of up to 20mg THC.

CBD Interaction with Pharmaceutical Drugs

  • CBD may alter action on metabolic enzymes (certain drug-transport mechanisms), and as such may alter interactions with other drugs, some of which may produce therapeutic or adverse effects. For instance, CBD interacts with the enzyme cytochrome P450 3A4 and cytochrome P450 2C19, increasing the bioavailability of anti-epileptic drugs such as clobazam (a benzodiazepine). This makes it possible to achieve the same results at significantly lower dosages, reducing treatment costs and risks of adverse effects. 
  • Groups of drugs affected include: anti-epileptic drugs, psychiatric drugs, and drugs affecting metabolic enzymes, for example.
  • Clinical observations suggest no likely interactions with other pharmaceuticals at a total daily dose of up to 100mg CBD

Dosing Considerations

THC Dosage Considerations

  • THC micro dose:  0.1 mg to 0.4 mg
  • THC low dose:  0.5 mg to 5 mg
  • THC medium dose:  6 mg to 20 mg
  • THC high dose:  21 mg to 50+ mg

CBD Dosage Considerations

  • CBD low dose:  0.4 mg to 19 mg
  • CBD medium dose: 20 mg to 99 mg
  • CBD high dose:  100 mg to 800+ mg (upper limits tested ~1,500mg)
