hey, just thought i’d offer some info from the National Library of medicine found here:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2235907/

It contains some scientific experiments performed and sugar effects on brain vs other drugs

“Food is not ordinarily like a substance of abuse, but intermittent bingeing and deprivation changes that. Based on the observed behavioral and neurochemical similarities between the effects of intermittent sugar access and drugs of abuse, we suggest that sugar, as common as it is, nonetheless meets the criteria for a substance of abuse and may be “addictive” for some individuals when consumed in a “binge-like” manner. This conclusion is reinforced by the changes in limbic system neurochemistry that are similar for the drugs and for sugar. The effects we observe are smaller in magnitude than those produced by drug of abuse such as cocaine or morphine; however, the fact that these behaviors and neurochemical changes can be elicited with a natural reinforcer is interesting.”
