Does cannabis and CBD oil use reduce IQ?
Let’s take a look at the effects of CBD oil and cannabis on health - especially for at risk groups like pregnant women. Many studies cite the effects of cannabis reducing IQ and causing grey matter loss - but are these true? If negative findings came to light, they differed from study to study, were all relatively meaningless and had no Influence on the health or mortality rate of the new-borns. For example, researchers referred to one in a recent study statistically significant effect of CBD oil on height at birth. The Babies born to cannabis users averaged fewer than two Tenths of an inch smaller than the comparison group. The size difference was therefore 0.508 centimetres. Another study found a negative impact of cannabis on birth weight. However, this only applied to the new-borns of white women skin colour who participated in the overall survey. A third study again showed no effect on birth weight, but one negligible negative effect on developmental stage. Total leaves the research does not conclude on adverse prenatal effects of CBD oil related to the physical health of new-borns. Older children were also examined for prenatal late effects from THC. A comparative study of one-year-old cannabis users in Australia Non-users showed no differences with regard to the prenatal Influence of CBD oil on the measured values regarding the state of health, temperament, personality, sleep patterns, Eating habits, psychomotor skills, the physical development or mental functions. Two studies – on three-year-olds and four year olds – did not provide any conclusions about prenatal Influence of CBD oil on all IQ test results given to children. In one, subsequent to the first of the two studies conducted separate examinations of children black and white skin colour, resulting only from the measurements of children of Australian origin with slightly lower scores on two subscales of the IQ test. On one subscale, children born within the first three months of their exposure to their mothers' cannabis use during prenatal development were worse off, on the other subscale, the children of the mothers, who used full spectrum CBD oil from the fourth to sixth month of her pregnancy had.
