    Does Vyvanse Get You High?

    Vyvanse is an amphetamine and yes, it can surely get you high!

    But, you should understand that each individual responds differently to different levels of doses.

    Sometimes, you may only have some milder effects like tooth grinding, foot tapping and babbling too much.

    The high is really peaceful (in some cases) and gives you a feeling of euphoria.

    Since it is being used to treat ADHD (4), people have reported incredible mood lift, motivation, and increased concentration for a long time. The user may feel very energetic and the productive hours has been known to increase manifold.

    If you are high on Vyvanse, you may feel like you are the king of the world and you may get a staggering desire to sprint all around.

    People taking 50mgs of Vyvanse have claimed to experience very relaxing effects.

    It may make the world seem bright and fuzzy to you.

    You Should Know:

    1. Amphetamine takes a longer time to get in your system because it needs to get metabolized first.
    2. Vyvanse is a prodrug (5) of amphetamine (lisdexamfetamine) and takes almost about an hour to get converted into dextroamphetamine.
    3. This is a genuine virtuoso with respect to the producer since it makes its recreational abuse (snorting, plugging, shooting, crushing) almost impossible.
    4. It takes several hours to reach the peak effects.
    5. It remains inactive until taken orally. (So, don’t do something dumb like snorting it and let your liver do its work!)

    Adderall High vs. Vyvanse High

    Both Adderall and Vyvanse have been categorized under “Schedule II” which means that they have the potential for abuse and their prolonged use may result in drug dependence.

    So, Is there any difference between ‘Adderall High’ and ‘Vyvanse High’?

    Let’s Find Out!

    Well, If we compare the effects of both these drugs, we can surely find some dissimilarities in their effects.

    To start with, Vyvanse is a pure dexamphetamine whereas Adderall is 70% dex 30% lis.

    ➸The effects of Vyvanse are known to last for 10-12 hours compared to Adderall’s 5-6 hour effects.

    ➸Vyvanse is generally considered ‘smoother’ than Adderall due to the gradual increase in intensity compared to Adderall.

    ➸‘Vyvanse high’ is generally more body oriented compared to that of Adderall. Still, there is a nicer positive mood lift and an increased empathy associated with Vyvanse.

    ➸Those who tend to use amphetamine for recreational purposes prefer Adderall over Vyvanse since the latter takes a longer time to produce the effects (and 12 hours is too long a period for them to be stimmed out that way).

    ➸Since Adderall is known to produce an immediate effect it has a higher potential for abuse whereas Vyvanse produces a noticeably delayed effect.

    ➸Also, most users snort Adderall for a greater “high”.

    All things considered, Vyvanse is utilized into 100% dextroamphetamine, though Adderall is just 75% dextroamphetamine and 25% levoamphetamine; it could be concluded that the presence of levoamphetamine may make Adderall less addictive.

    Did You Know?

    Vyvanse is considered proportionate to somewhat less than half of its comparable Adderall weight because the extended of discharge moderates the initiation of amphetamine and it contains some portion of amino acid.

    (For instance, a 70mg Vyvanse is considered generally identical in strength to a 30 mg IR Adderall with double the duration.)

    When to seek medical help?

    • The individuals who are taking (MAOI) monoamine oxidase inhibitor (which is an antidepressant medicine) can have allergic reactions with the Vyvanse high dose.
    • Seek your doctor’s help if your child shows signs of chest pain, heartburn, fainting (while having Vyvanse).
    • Call your Doctor immediately if you see some unexpected wounds on your fingers and your toes.
    • Check for the growth and height of your child if he is having Vyvanse medicine. If the growth of your child has stopped, then you should immediately consult the Doctor.
    • If you or your child (whoever is taking the drug) faces numbness in the extremities, fingers, or toes, you should seek medical help.
    • If you are having severe pain in your hands and feet and you are experiencing high body temperature, you should consult your Doctor.
