Nigeria has been debating whether or not to legalise marijuana. Its House of Representatives is set to focus on a invoice to that impact. The Conversation Africa’s Wale Fatade requested Olakunle Idowu, a Professor of pharmaceutical chemistry, to clarify the science behind the talk.
Is there any scientific foundation for legalising marijuana?
The plant, Cannabis sativa, or Cannabis indica, accommodates a number of phytochemicals – cannabinoids – with a number of pharmacological actions. Its a number of results are the rationale some folks use marijuana and likewise the rationale others really feel it shouldn’t be legalised. While it offers some a pleasurable impact, the energetic doses even have a number of unwanted effects.
A specific phytochemical – delta-9-tetrahydrocannabinol (THC) – discovered within the leaves, flower and resin produced by the plant, is responsible for the euphoria that customers of marijuana expertise. It reacts with particular receptors within the brain. This “high” is usually related to dependancy and crime.
On the opposite hand, cannabidiol (CBD), additionally discovered within the plant, is a compound that doesn’t work together with that receptor. It doesn’t have an effect on a particular person’s psychological state, however has properties which are shown to be useful for managing anxiousness and epilepsy.
Cannabidiol oil is commercially accessible in some pharmacies in Nigeria. It is offered as a dietary complement.
To complicate the image, the potential results of the chemical compounds on folks depend upon the plant selection, the cultivar. The cultivar that’s grown as industrial hemp for fibre and biodiesel is much richer in CBD than THC.
In essence, legalising marijuana would imply addressing some scientific points for security causes. These are:
figuring out the precise number of the hashish plant within the nation, and
the portions of the phytochemicals – THC and CBD – current in these varieties. Geography (terrain, soil high quality and chemistry) affects the composition and relative quantities of plant phytochemicals.
What scientific challenges would Nigeria face in legalising marijuana?
One problem is to have the scientific functionality to consider what’s authorized and decide what is prohibited.
In the US, cannabidiol, which doesn’t produce the “high”, is legal if it accommodates 0.3% or much less of THC, the chemical that produces the “high” with the related delinquent impact. This comes down to “quantitative phytochemistry” – the flexibility to precisely and reliably decide how a lot of a particular phytochemical is present in a plant pattern.
When THC is above the extent specified, will probably be dominated unlawful. This degree of specification is required as a result of it’s the THC focus that’s related to the propensity for drug abuse and crime.
Reliable outcomes from quantitative phytochemistry depend upon hint evaluation, which requires instrumental strategies of research, primarily based on laboratory gear which is dear to purchase and keep. In most circumstances the analytical methodology used is liquid chromatography hyphenated with mass spectrometry (LC-MS-MS), a specialised approach that’s not but commonplace in Nigeria.
If marijuana had been authorized, the drug regulatory company, the National Agency for Drug Administration and Control, would in all probability have an elevated burden of duty.
Quality assurance could be a severe problem. For a plant product that has a vast disparity in pharmacological actions, it’s troublesome to have a protected energetic dose with out unwanted effects. It can have very completely different results on completely different folks, so “abundance of caution” is the wiser method to undertake.
As a scientist, do you assist the legalisation of marijuana in Nigeria?
In my view we should always not legalise marijuana but, when there may be little to no analysis information in our universities on the plant, particularly the varied cultivars that develop in our surroundings.
We ought to quite begin with a mandate for the National Agency for Drug Administration and Control to coordinate analysis actions throughout pharmacy colleges within the nation to develop validated analytical strategies to do quantitative phytochemistry. Then we are able to decide the degrees of CBD and THC in a pattern. The company will want these competencies to decide what’s protected and what’s not, when counterfeiting begins. Lawsuits will come down to these analytical capabilities, when there may be perceived contravention of no matter legal guidelines are handed.
An identical scenario arose within the US in 1994, when the Dietary Supplements Health and Education Act was signed. The office of Dietary Supplements was arrange in 1995 to implement the brand new legislation and promote protected and accountable use of dietary dietary supplements in that nation.
The dialog in Nigeria ought to begin with what science is required and what scientific functionality the nation has. That may safely drive the legality of marijuana use in our nation.
