Overview - Longevity

Description of Longevity

According to family research on average only about 25% of what induces longevity has a genetic basis making environmental factors the most significant factors that determine lifespan [Source–Hum Genet. 119(3):312-21]. What is empowering about these findings is that many of the environmental factors that contribute to longevity may be subject to conscious intervention. In other words, we can choose them.

There are several methods or processes that have been posited to be able to extend life at the level of the individual cell and for the whole organism. Here we'll focus mostly on the aspects of cognitive decline (e.g., dementia), facilitation of molecular clearance (i.e., optimization of autophagy e.g., in Alzheimer's disease), homeostatic defense activities, re-establishing optimal homeostatic processes, mitigating neurodegeneration and/or neuro-inflammation (incl. neurogenesis), countering excessive oxidative stress, SIRT activation, caloric restrictions, mind-body approaches, and other modulations via the endocannnabinoidome.

Disease Classification

Condition: Longevity
Disease Family:
Organ System: Integumentary System
ICD-10 Chapter: N/A
ICD-10 Code: N/A

Longevity Symptoms:

Slowing, reversing, mitigating or reducing physical signs and symptoms of aging such as wrinkles, “age spots,” greying hair, loss of muscle mass, loss of height, weight gain (associated with metabolic syndrome, insulin resistance, diabetes), loss of visual focus, loss of energy (i.e., at the level of the cell and the whole body), longer recovery times, male/female menopause, epigenetic changes, mutation, telomere shortening, loss of genetic stability and DNA repair capacities, loss of optimal organ/system functions, dysfunctional autophagy, mitochondrial dysfunction, dysfunction of the ECS, increased vulnerability to develop chronic degenerative illness associated with aging such as cancer, cardiovascular diseases, osteoporosis, and obesity. Slowing, reversing, mitigating or reducing mental-emotional signs and symptoms of sub-optimal ageing may include cognitive decline or dysfunction (e.g., on a spectrum between forgetfulness–dementia), social isolation (e.g., loneliness, hopelessness), mood disorders (e.g., depression, anxiety, rapid fluctuations in mood), ruminating (esp. at night), lack of mental-emotional energy and/or focus, loss of social skills and/of functions.

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 (0.001mg/kg to 0.005mg/kg)
  • THC low dose:  0.5 mg to 5 mg (0.006mg/kg to 0.06mg/kg)
  • THC medium dose:  6 mg to 20 mg (0.08mg/kg to 0.27mg/kg)
  • THC high dose:  21 mg to 50+ mg (0.28mg/kg to 0.67mg/kg)
Formula for converting a set dose into mg/kg considerations: mg ÷ kg = mg/kg
(sample conversion calculated on a person weighing 75kg)

CBD Dosage Considerations

  • CBD low dose:  0.4 mg to 19 mg (0.005mg/kg to 0.25mg/kg)
  • CBD medium dose: 20 mg to 99 mg (0.26mg/kg to 1.32mg/kg)
  • CBD high dose:  100 mg to 800+ mg (1.33mg/kg to 10.7mg/kg)
  • (upper limits tested ~1,500mg)
Formula for converting a set dose into mg/kg considerations: mg ÷ kg = mg/kg
(sample conversion calculated on a person weighing 75kg)
