Quality assessment, statistical methods, and optimized methods for data management are also discussed. An assessment of current and emerging dietary supplement characterization methods is provided, including targeted and non-targeted techniques, as well as data analysis and evaluation approaches, with a focus on chemometrics, toxicity, dosage form performance, and data management. This article discusses the utility of applying rigorous analytical techniques and adopting metrological principles more widely in studying dietary supplement products and ingredients, particularly medicinal plants and other botanicals. Yet, metrology is often underappreciated and underutilized in dealing with the many challenges presented by these chemically complex preparations. Canberra: Australian Institute of Health and Welfare.The increased utilization of metrology resources and expanded application of its’ approaches in the development of internationally agreed upon measurements can lay the basis for regulatory harmonization, support reproducible research, and advance scientific understanding, especially of dietary supplements and herbal medicines.

Leonard, W., Dowsett, G., Slavin, S., Mitchell, A., & Pitts, M.Withdrawal symptoms generally settle down after a week and will mostly disappear after a month. Giving up ice after using it for a long time is challenging because the body has to get used to functioning without it. The stimulant effects of ice may mask the effects of depressant drugs like benzodiazepines and can increase the risk of overdose.
Ice + alcohol, cannabis or benzodiazepines : enormous strain on the body, and more likely to overdose.Ice + speed or ecstasy : enormous strain on the heart and other parts of the body, which can lead to stroke.The effects of taking ice with other drugs − including over-the-counter or prescribed medications − can be unpredictable and dangerous, and could cause: People may feel these effects for at least several weeks or months after they give up ice. These changes can lead to longer-term problems with anxiety and depression. They can get stressed easily and their moods can go up and down quite quickly. Some people who regularly use ice may start to feel less enjoyment of everyday activities. They may feel they need ice to go about their normal activities like working, studying and socialising, or just to get through the day. People who regularly use ice can quickly become dependent on the drug. These symptoms usually disappear a few days after the person stops using ice. High doses of ice and frequent use may result in a psychological condition known as ‘ice psychosis’, characterised by paranoid delusions, hallucinations and bizarre, aggressive or violent behaviour. needing to use more to get the same effect.extreme weight loss due to reduced appetite.With regular use, ice may eventually cause: Using a depressant drug such as alcohol, benzodiazepines or cannabis to help with the come-down effects may result in a cycle of dependence on both types of drugs. headaches, dizziness and blurred vision.The following effects may be experienced during this time: It can take several days to come down from using ice.
