Tina is cur­rent­ly the most pow­er­ful stim­u­lant sold in the Netherlands.
The inten­si­ty of its effect is more than three times that of cocaine (see table).
It floods the brain with dopamine, gen­er­at­ing an intense feel­ing of euphoria.
You also feel ener­gised and confident.
Its effect is often described as “over­whelm­ing” and “incred­i­bly sex­u­al­ly arousing”.
This sounds appeal­ing, but reg­u­lar use comes with a major downside.


It blurs your per­cep­tion of time, and sup­press­es your need for food and sleep.
Sex under the influ­ence of Tina can some­times go on for days.


Its effect, once it wears off, is often fol­lowed by an intense and pro­longed hang­over, oth­er­wise known as “com­ing down”.
The dura­tion of this dip depends on how much you took, how long you took it for, and whether or not you took it in com­bi­na­tion with oth­er substances.
Many users expe­ri­ence phys­i­cal, men­tal and sex­u­al dis­com­fort for days afterwards.
Symp­toms include exhaus­tion, insom­nia, depres­sion, anx­i­ety, severe mood swings and a dimin­ished libido.
These symp­toms can per­sist for a week or longer.

Effects of long-term use



Tak­ing crys­tal meth is an extreme assault on the body, mind and brain.
The more often and more inten­sive­ly you use it, the soon­er you expe­ri­ence its neg­a­tive effects and the soon­er you become men­tal­ly dependent.
The intense “high” is often fol­lowed by a sim­i­lar­ly intense “low”.


The fol­low­ing fac­tors large­ly deter­mine the extent and type of neg­a­tive effects, and the like­li­hood of dependence:

  • Usage method: are you snort­ing, ingest­ing oral­ly, smok­ing, booty bump­ing or slam­ming your Tina?
  • Quan­ti­ty and fre­quen­cy: how often and how much do you use?
  • Lifestyle: do you take suf­fi­cient breaks, and take in enough food and drink when you use?
  • Phys­i­o­log­i­cal pre­dis­po­si­tion: some men are more sen­si­tive to crys­tal meth than others.
  • Your cir­cum­stances: do you already suf­fer from depres­sion or heart prob­lems, or are you social­ly isolated?





A lot of guys who use crys­tal meth on a reg­u­lar basis when hav­ing sex even­tu­al­ly find it hard to have sex with­out it.


Symp­toms of long-term use:

Over­stim­u­la­tion, sleep depri­va­tion and deple­tion of brain chem­i­cals can even­tu­al­ly lead to:

  • Dimin­ished libido
  • Depres­sion and sui­ci­dal thoughts
  • Con­tin­u­ous stress and irritability
  • Para­noia and psychosis


Oth­er poten­tial long-term consequences:

  • Mal­nu­tri­tion and dimin­ished resis­tance to illness/li>
  • Kid­ney damage
  • Break­down of mus­cle tissue
  • Tooth decay
  • Dry and intense­ly itchy skin
