In 2019, the cannabis manufacturer, Canopy Growth, acquired majority ownership of BioSteel Sports Nutrition, which is developing CBD products under endorsement by numerous professional athletes. The National Hockey League Alumni Association began a project with Canopy Growth to determine if CBD or other cannabis products might improve neurological symptoms and quality of life in head-injured players. Numerous professional athletes use CBD, primarily for treating pain. Legal status
Australia
Prescription medicine (Schedule 4) for therapeutic use containing two percent (2.0%) or less of other cannabinoids commonly found in cannabis (such as ∆9-THC). A Schedule 4 drug under the SUSMP is a Prescription Only Medicine, or Prescription Animal Remedy – Substances, the use or supply of which should be by or on the order of persons permitted by state or territory legislation to prescribe and should be available from a pharmacist on prescription.In June 2020, the Australian Therapeutic Goods Administration (TGA) published a consultation on a proposal to pave the way to make "low dose" CBD available to consumer/patients via pharmacists only through moving products from Schedule 4 to 3. Any products sold would need to have their safety, quality and efficacy pre-assessed by the TGA and be formally approved for sale (details to be outlined by TGA). They would be made available to over 18s only, with the maximum daily dose of 60 mg/day, up to 2% THC finished product allowed, 30-day maximum supply, plant-derived or synthetic.
At the start of the fetal stage, the fetus is typically about 30 millimetres (1+1⁄4 in) in length from crown-rump, and weighs about 8 grams. The head makes up nearly half of the size of the fetus. Breathing-like movements of the fetus are necessary for the stimulation of lung development, rather than for obtaining oxygen. The heart, hands, feet, brain and other organs are present, but are only at the beginning of development and have minimal operation.At this point in development, uncontrolled movements and twitches occur as muscles, the brain, and pathways begin to develop. Weeks 17 to 25 (3.6 to 6.6 months)
A woman pregnant for the first time (nulliparous) typically feels fetal movements at about 21 weeks, whereas a woman who has given birth before will typically feel movements by 20 weeks. By the end of the fifth month, the fetus is about 20 cm (8 in) long. Weeks 26 to 38 (6.6 to 8.6 months)
The amount of body fat rapidly increases. Lungs are not fully mature. Neural connections between the sensory cortex and thalamus develop as early as 24 weeks gestational age, but the first evidence of their function does not occur until around 30 weeks, when minimal consciousness, dreaming, and the ability to feel pain emerges. Bones are fully developed, but are still soft and pliable. Iron, calcium, and phosphorus become more abundant. Fingernails reach the end of the fingertips. The lanugo, or fine hair, begins to disappear, until it is gone except on the upper arms and shoulders.
