The realm of nootropic substances (aka cognitive enhancers or smart drugs), at the time around its conception, was reserved for the very select few who had access to these novel cognition-enhancing drugs. In recent years, nootropics have gained more widespread recognition, and are more accessible to average individuals than ever before, thanks to the rising number of online vendors and communities who make these substances accessible for all.
The term “nootropic” has been consistently more and more searched on google ever since 2011 (the year when the film Limitless was released) , and people’s interest in the subject will certainly continue to rise. Although nootropics still maintain a type of “fringe” status in the world of drugs, their infiltration into the mainstream is undeniable.
What is a Nootropic?
Corneliu E. Giurgea, the Romanian chemist who first synthesized piracetam, developed the concept of nootropic substance in 1972. It is a combination of the Greek words “νους” (nous) meaning “mind”, and “τρoπoς” (tropos) meaning “bend” or “change”. This is what nootropics do. Essentially, they positively alter the way in which your mind works.
Nootropic drugs are a specific subtype of psychoactive substances. According to Giurgea, in order for a drug or supplement to be considered a nootropic, it must adhere to the following criteria:
- Enhances learning and memory
- Enhances resistance of learned behaviors to conditions that will disrupt them
- Protects the brain against physical of chemical injuries (such as concussions or neurotoxic drugs)
- Increases the efficacy of cortical/subcortical control mechanisms of the brain (such as improving reaction time)
- Typically lacks negative side-effects (i.e. sedation), and possesses low toxicity
Though these criteria lay out the foundation for what a nootropic is, most modern definitions are much more general. As a more common definition, nootropics are chemical substances or herbal supplements that enhance cognition and mental function.
If we think in terms of this general definition, there is about a 90% chance you use a pseudo-nootropic substance regularly. Caffeine, the most popular drug in the world, is commonly classified as a nootropic, due to the fact that it is stimulatory and enhances attentiveness linked to cognition, learning, and memory.  
Certain substances that don’t explicitly enhance cognition are still sometimes grouped in with nootropics. This would include substances that improve mood, reduce anxiety, or promote an overall feeling of wellbeing. Some examples of these substances are phenibut, sulbutiamine, and ashwagandha. Even if these supplements don’t have mechanisms that directly improve cognition, their mood-improving capabilities will tend to lead to an enhanced ability to focus and think clearly.
Who Uses Them?
Giurgea coined the term “nootropic” after he synthesized piracetam, which is, under Giurgea’s definition, the first substance to display purely nootropic properties. Piracetam has cognitive enhancing and neuroprotective capabilities while also possessing relatively few side effects.  Because of this, piracetam is commonly used to improve cognition in individuals who are experiencing the cognitive decline that comes with old age, dementia, or Alzheimer’s.
With the development of piracetam, other nootropic substances were investigated and researched for their applications in those who experience cognitive decline. Many drugs derived from piracetam (referred to as “racetams“) have been developed in hopes that they would yield even more benefits than piracetam. For instance, phenylpiracetam displays stimulant properties in addition to cognitive enhancement.  Likewise, aniracetam works as an anxiolytic. 
Up until the past decade, these kinds of cognitive-enhancing drugs were only used extensively in clinical applications, such as treating cognitive illnesses. However, the past few years have seen tremendous growth in the use of nootropics among younger healthy individuals in hopes that they could improve their performance in work or academic studies. For example – modafinil (Provigil), a wakefulness-promoting nootropic substance, has seen increased usage among college students as an alternative to Adderall, due to the fact that it aids the brain in focusing on tasks for extended periods of time without fatigue. 
Many nootropic substances, such as the racetams and tianeptine (an antidepressant nootropic), are prescription drugs in Europe but are unscheduled in the United States. This has led to many of them being sold online by nootropic vendors, making them readily available for those who wish to purchase them.
Not surprisingly, Russia, the country that has developed a large number of nootropics (including Phenibut, Picamilon, Phenylpiracetam, Selank, Semax, Cerebrolysin, Emoxypine and so on), it’s the place where the keyword “nootropic(s)” is most popular in 2016, according to Google.
The increasing number and growth of online communities, such as the nootropics subreddit, has attracted the attention of younger individuals who seek to improve their cognitive performance and preserve their youthful cognitive capabilities. These online communities are extremely valuable sources of information on all things related to nootropics. They are open forums where anyone can ask questions about smart drugs and cognitive enhancement and engage in valuable discussion. Many newer nootropic substances have not been extensively tested in clinical settings, but anecdotal user reports can be found within these online communities.
Where Do I Begin?
If you are determined to make a go at nootropic supplementation, then logically the smart thing to do is implement the smartest ways to use smart drugs. You do not have to be a brain surgeon to begin effectively supplementing with nootropics, but understanding at least the bare bones of the foundations of a few related fields like neuroscience, neurology, and drug metabolism, is vital to getting the most out of them.
Ideally, you want a good working understanding of all the major mechanisms of action, including receptor systems involved in memory, mood and cognition (dopamine, GABA, acetylcholine, serotonin, etc). Attempting anything other could end up as catastrophically as fiddling with the kernel of your operating system without knowing how it works. The best way to go about it is to learn what happens to drugs inside the body, how the classic nootropics work (like Piracetam and Aniracetam), and what are some of the basic nootropic stacks.
Even though it can be a bit daunting at first, you will also want to learn how to access & read scientific research, what is acetylcholine (the learning and memory neurotransmitter), how it works, how the brain produces it and what is a choline precursor. Learning the major neurotransmitters, understanding the difference between excitatory and inhibitory neurotransmitters, all these are great places to start.
