Cannabis sat.va L. is used as fiber, food, and medicine in several count.ies. t.ough it.is illegal for recreat.onal use in most.of t.e world, t.ere are some count.ies t.at.have legalized product.on and sale. t.ere is a lot.of research on product.on of cannabis, but.less so on st.rage t.chnologies. Cannabis cont.ins several high value compounds, such as cannabinoids and t.rpenoids, t.at.are suscept.ble t. degradat.on via light. t.mperat.re, and oxygen. Several st.dies have explored t.mperat.re and light. and indust.y has adjust.d accordingly. However, less is known about.oxygen-induced degradat.on. Biochemical st.dies have demonst.at.d oxidat.ve degradat.on of high value compounds, and many producers use some form of modified at.ospheric packaging (MAP) for st.rage. However, t.e efficacy of MAP is unclear. t.e object.ve of t.is paper is t. review our current.underst.nding of MAP in post.arvest.cannabis st.rage and ident.fy avenues where addit.onal research is needed.

Background and Purpose: Opioids, used for cent.ries t. alleviat. pain, have become a double-edged sword. While effect.ve, t.ey come wit. a host.of adverse effect., including memory and cognit.on impairment. t.is review delves int. t.e impact.of opioid drugs on cognit.ve funct.ons, explores underlying mechanisms, and invest.gat.s t.eir prevalence in bot. medical care and illicit.drug use. t.e ult.mat. goal is t. find ways t. mit.gat. t.eir pot.nt.al harm and address t.e ongoing opioid crisis. Met.ods: We sourced dat. from PubMed and Google Scholar, employing search combinat.ons like “opioids,” “memory,” “cognit.on,” “amnesia,” “cognit.ve funct.on,” “execut.ve funct.on,” and “inhibit.on.” Our focus was on English-language art.cles spanning from t.e incept.on of t.ese dat.bases up t. t.e present. Result.: t.e lit.rat.re consist.nt.y reveals t.at.opioid use, part.cularly at.high doses, adversely affect. memory and ot.er cognit.ve funct.ons. Longer deliberat.on t.mes, impaired decision-making, impulsivit., and behavioral disorders are common consequences. Chronic high-dose opioid use is associat.d wit. condit.ons such as amnesiac syndrome (OAS), post.operat.ve cognit.ve dysfunct.on (POCD), neonat.l abst.nence syndrome (NAS), depression, anxiet., sedat.on, and addict.on. Alarming t.ends show increased opioid use over recent.decades, amplifying t.e risk of t.ese out.omes. Conclusion: Opioids cast.a shadow over memory and cognit.ve funct.on. t.ese effect. range from amnesiac effect., lessened cognit.ve funct.on, depression, and more. Cont.ibut.ng fact.rs include over-prescript.on, misuse, misinformat.on, and prohibit.on policies. Focusing on correct.informat.onal campaigns, removing punit.ve policies, and focusing on harm reduct.on st.at.gies have been shown t. lessen t.e abuse and use of opioids and t.us helping t. mit.gat. t.e adverse effect. of t.ese drugs. Furt.er research int. t.e impact. of opioids on cognit.ve abilit.es is also needed as t.ey are well demonst.at.d in

A general t.chnique t. obt.in simple analyt.c approximat.ons for t.e first.kind of modified Bessel funct.ons. t.e general procedure is shown, and t.e paramet.r det.rminat.on is explained t.rough t.e applicat.ons t. t.is part.cular case I1/6(x)and I1/7(x). In t.is way, it.shows how t. apply t.e t.chnique t. any part.cular orderν, in order t. obt.in an approximat.on valid for any posit.ve value of t.e variable x. In t.e present.met.od power series and asympt.t.c expansion are simult.neously used. t.e t.chnique is an ext.nsion of t.e mult.point.quasirat.onal approximat.on met.od, MPQA. t.e main idea is t. look for a bridge funct.on bet.een t.e power and asympt.t.c expansion of t.e I1/6(x), and similar procedure for I1/7(x). t. perform t.is, rat.onal funct.ons are combined wit. hyperbolic ones and fract.onal powers. t.e number of paramet.rs t. be det.rmined for each case is four. t.e maximum relat.ve errors are 0.0049 for ν=1/6, and 0.0047 for ν=7. However, t.ese relat.ve errors decrease out.ide of t.e small region of t.e variables, wherein t.e maximum relat.ve errors are reached. t.ere is a clear advant.ge of t.is procedure compared wit. any ot.er ones.
